Amazing facts about dreams that you should know

Below are some amazing facts about dreams that you should know, let's have a closer look at 

1. Dream tenure


An average human being spends 6 whole years of his/her life dreaming, from coolfunfactsoflife.

2. Memory limit


There's a time limit to how much you can remember about your dream. Only within five minutes since you are up from your sleep, an average person's dream is forgotten and in just 10 minutes, 90 percent of the dream is gone with the wind. However, if awakened at the REM (rapid eye movement sleep) stage, that person is more likely to remember the dream.

3. Eyes don't matter


Blind people can dream. People who became blind after birth can see images in their dreams and those who were born blind dream as vividly, however, instead of seeing images, they use their other senses such as smell, sound, touch etc. to dream.

4. Dream Master


The good part is that you can often control your dreams. You can manipulate, twist and turn the beginning and the ending of your dreams like it's a movie being shot in front of you. It is called the "Lucid dreaming" (one is aware that he/she is dreaming) phase.

5. Entry level


Toddlers don't star in their own dreams till they are about 3-4 years old.

6. Dreams are for everyone


There is not one person who doesn't dream, except those who have psychological disorders. If you think you don't dream, it's just that you're forgetting your dreams. That might be one of the most awesome interesting facts ever.

7. Familiarity


You might not remember the person in your dream. However, a person only dreams of people he/she has encountered in life but it's impossible to keep track of thousands of faces that you come across each day.

8. Colour no bar


Not everyone dreams in colour and not everyone dreams in black and white. If a person grew up watching black and white television, he/she is more likely to dream in black and white. In a survey, it was revealed that 12% of sighted people ONLY dreamt in black and white and rest of the sample dreamt exclusively in colour. The number has gone down. Today, only 4.4% under-25-year olds dream in black and white, the change is being based (by scientists) upon the transformation from black and white television to colour media.

9. Symbol


You sometimes have the strangest of dreams - some scary, some worrisome and the rest absolutely angelic. Remember, these are all symbols for something or the other. There's nothing strange about these dreams because they are only talking in a symbolic language like poems. Check out my list of fun, weird and just plain amazing fact of life I have found.

10. Universal


It's not only you who dreams, animals dream too just like this leopard lost in his dreamworld after eating lunch. The best example is a dog, you will often see them twitching their paws as if they are running in their dreams.

How do clouds form?

Keep the learning going about by checking out one or more amazing information with a friend or family member: How do clouds form?


Clouds are made of tiny drops of water or ice crystals that settle on dust particles in the atmosphere. The droplets are so small - a diameter of about a hundredth of a millimetre - that each cubic metre of air will contain 100 million droplets.

Clouds will either be composed of ice or water droplets depending on the height of the cloud and the temperature of the atmosphere. Because the droplets are so small, they can remain in liquid form in temperatures as low as -30 °C. Extremely high clouds at temperatures below -30 °C are composed of ice crystals.

Enjoy our wide range of funny pictures with captions that can make a joyful day.

How do clouds form?

Clouds form when the invisible water vapour in the air condenses into visible water droplets or ice crystals. There is water around us all the time in the form of tiny gas particles, also known as water vapour. There are also tiny particles floating around in the air - such as salt and dust - these are called aerosols.

The water vapour and the aerosols are constantly bumping into each other. When the air is cooled, some of the water vapour sticks to the aerosols when they collide - this is condensation. Eventually, bigger water droplets form around the aerosol particles, and these water droplets start sticking together with other droplets, forming clouds.

Clouds form when the air is saturated and cannot hold any more water vapour, this can happen in two ways:
The amount of water in the air has increased - for example through evaporation - to the point that the air cannot hold any more water.
The air is cooled to its dew point - the point where condensation occurs - and the air is unable to hold any more water.

The warmer the air is, the more water vapour it can hold. Clouds are usually produced through condensation - as the air rises, it will cool and reducing the temperature of the air decreases its ability to hold water vapour so that condensation occurs. The height at which dew point is reached and clouds form is called the condensation level.

What causes clouds to form?

1. Surface heating - This happens when the ground is heated by the sun which heats the air in contact with it causing it to rise. The rising columns are often called thermals. Surface heating tends to produce cumulus clouds.

2. Topography or orographic forcing - The topography - or shape and features of the area - can cause clouds to be formed. When air is forced to rise over a barrier of mountains or hills it cools as it rises. Layered clouds are often produced this way.

3. Frontal - Clouds are formed when a mass of warm air rises up over a mass of cold, dense air over large areas along fronts. A 'front' is the boundary between warm, moist air and cooler, drier air.

4. Convergence - Streams of air flowing from different directions are forced to rise where they flow together, or converge. This can cause cumulus cloud and showery conditions.

5. Turbulence - A sudden change in wind speed with height creating turbulent eddies in the air.

The range of ways in which clouds can be formed and the variable nature of the atmosphere results in an enormous variety of shapes, sizes and textures of clouds. To find out more about different types of clouds and how you can identify them, read our cloud spotting guide.

The best collection of Gibbon facts

The best collection of Gibbon interesting facts:

Gibbon is a small ape. Its closest relatives are gorilla, chimpanzee, orangutan and bonobo. There are 15 species of gibbons that can be found in Southeast Asia (China, India, Burma, Malayan peninsula, Borneo…). Gibbon lives in dense jungles and tropical rainforests.

Gibbon facts

  • Gibbons spend almost all of their time in the treetops of the rainforest. They even sleep there, resting in the forks of branches.
  • Their dramatic form of locomotion, called brachiating, can move gibbons through the jungle at up to 35 miles (56 kilometers) an hour, bridging gaps as wide as 50 feet (15 metres) with a single swinging leap.
  • Because they are not able to swim, different types of gibbons are isolated in different areas by large rivers.
  • When gibbons walk, whether along branches or in the rare instances when they descend to the ground, they often do so on two feet, throwing their arms above their head for balance.
  • They are the most bipedal of all non-human primates and are often studied for clues to what evolutionary pressures may have led to human walking.
  • There are 15 recognized species of gibbons ranging from northeastern India to southern China to Borneo. Let’s discover some interesting science facts that will amaze you.
  • Gibbons are omnivores (they eat both plants and animals). Their diet consists mainly of fruit, but they also eat different types of seed, shoots, flowers and insects.
  • Gibbons live in family groups composed of breeding couple and their offspring. Gibbons are monogamous (one couple mate for life) and they form very strong bonds with family members. Grooming plays important role in their social life.
  • Gibbons are territorial animals that usually live on a territory of 25 to 40 hectares. They fiercely defend their home.
  • Gibbons are highly intelligent animals. They can recognize themselves in the mirror. Also, they are able to communicate via various songs. Songs usually last 10 to 30 minutes and both males and females perform them. Main purpose of the song is to announce presence of the group on a certain territory.
Are you bored? Let’s have a quick look at our funny images that are bound to bring smile on your face.

Reacting cat bites and scratches

What should you do when being bitten by cats and other random facts about cats right here

1
React calmly. Never hit, shout, chase, or lose your temper with a cat. You will simply terrify the cat and cause it to become nervous and confused.
Never call a cat to you and then punish it. The cat hasn't got a clue why you're responding negatively to him. In fact, the cat probably expects a pleasant response if you call it.



2
Remove yourself from the situation. The first thing to do is stop touching the cat and then hold your hands well out of striking range. If he doesn't calm down within a few seconds, stand up slowly so you can remove him from your lap. Walk away and do not return until he has calmed down.
Avoid soothing your cat after biting or scratching. Instead, signal your displeasure to the cat. After you've disciplined it, do not begin cuddling and petting him. This will confuse your cat and give him mixed signals. It may even begin biting you in order to get a cuddle.

3
Give the cat a way out. If you are trying to get from one room to another and a hissing, snarling cat blocks the way, look at the situation from his viewpoint. The cat believes he is trapped and you are walking towards him, which he perceives as a threat. He wants to run but there is no escape route so he must defend himself by attacking. The simple solution is to step aside, let the cat pass (which he will do at speed) and then go about your way.
Don't feed your cat for 20 minutes following a biting or scratching incident, as this might be wrongly taken as a reward.

4
Understand what encourages a cat to change its behavior. Cats respond best to positive reinforcement, namely praising and rewarding appropriate behavior, while ignoring and withdrawing from inappropriate behavior.
Hand the cat a catnip mouse to bite instead of you. Then, praise the cat for biting the toy.

5
Try the voice and body method. As soon as the cat bites or scratches, say "NO!" in an authoritative tone. At the same time, point your finger at the cat. Stare at the cat directly with an unimpressed or fierce look. Stares are regarded in the cat world as a threat of dominance.
It also helps to remove yourself from the cat's vicinity after doing this, or to ignore him for about 10 minutes.

6
Try the hand clapping method. When your cat bites or scratches, clap your hands and say "NO!" firmly. Remember, don't shout at your cat or clap directly in your cat's face. It can scare him and leave him nervous. Repeat this whenever biting or scratching occurs. Your cat should learn to stop.
This method works with a dominant, aggressive or cheeky cat. It's not recommended for use with a timid or nervous cat, since it can reinforce these traits.

7
Try to ignore the cat. The moment your cat stops biting or scratching you, stand up and walk away in a dismissive fashion without any further interaction. Make sure that the cat is all alone in the room with no human interaction for 5 to 10 minutes. Repeat this each time he tries to bite or scratch you. He will quickly associate the bad behavior with being ignored.
This method won't work with all cats, but works well with very affectionate cats, since they'll miss the attention, and with kittens, since they're still learning manners.

Tuatara facts that will open your mind

Keep following to get more amazing information about animal facts. And here in this article, we round up and give you Tuatara facts that will open your mind

The tuatara may look like a rather ordinary reptile, but it’s a highly unusual creature. This New Zealand native has a unique, ancient lineage that goes back to the time of the dinosaurs.



1. The tuatara may look like a lizard, but it’s unique. The tuatara is not a lizard; it is the only living member of the order Rhynchocephalia, which flourished around 200 million years ago. All other members of the order became extinct 60 million years ago, in the late Cretaceous period.

2. The name “tuatara” comes from the Maori for “peaks on the back.”Tuataras have spiny crests along their backs made from soft, triangular folds of skin. These spines are more prominent in males, who can raise them during territorial or courtship displays.

3. They are surprisingly long-lived. Tuataras mature slowly and don’t stop growing until they reach about 30 years old. It is thought they can live up to 100 years in the wild. Part of the reason for their longevity may be their slow metabolism. Tuataras can tolerate much lower temperatures than most reptiles and they hibernate during the winter. The body temperature of tuataras can range from 41-52 °F over the course of a day, whereas most reptiles have body temperatures around 68 °F. This low body temperature results in a slower metabolism.

There exists a lot of amazing creatures in our world that are bound to make you surprise. Do you want to check out our long and rich source of tigers facts in your spare time?

4. They have a third eye. The tuatara has a third eye on the top of its head called the parietal eye. This eye has a retina, lens, cornea, and nerve endings, but it is not used for vision. The parietal eye is only visible in hatchlings, as it becomes covered in scales and pigments after four to six months. Its function is a subject of ongoing research, but it is believed to be useful in absorbing ultraviolet rays and in setting circadian and seasonal cycles.

5. They can regrow lost tails. The tuatara can break off its tail when caught by a predator and regenerate it later.



6. They have unusual teeth that can’t be replaced. Tuataras have a single row of teeth on the lower jaw and a double row of teeth on the upper jaw, with the bottom row fitting between the two upper rows when the mouth is closed. It’s a tooth arrangement not seen in any other reptile. And unlike all other living toothed reptiles, the tuatara’s teeth are not separate structures but sharp projections of the jaw bone. This means that worn down or broken teeth cannot be replaced. Older tuataras with worn-down teeth have to switch from eating hard insects to softer prey such as earthworms, larvae, and slugs.

7. Tuataras reproduce slowly. They take 10-20 years to reach sexual maturity. Males can mate every year, but females breed every two to five years. It takes the female between one and three years to provide eggs with yolk, and up to seven months to form the shell. Then it takes an additional 12 to 15 months from copulation to hatching, possibly the longest incubation rate of any reptile.

A male tuatara named Henry, living at the Southland Museum and Art Gallery, became a first-time father at the age of 111. He fathered 11 babies with a female named Mildred, believed to be in her seventies.

8. They’re diurnal when young, nocturnal as adults. Hatchling tuataras are believed to be active during the day to avoid the cannibalistic adult tuataras that come at out night.

9. They cohabitate with birds. Tuataras can dig their own burrows, but also use the burrows of seabirds for shelter when available. The seabirds’ guano provides an attractive environment for the invertebrates that tuataras prey upon, such as beetles, crickets, and spiders. Tuataras will also sometimes eat the eggs and young of the seabirds.

10. Tuataras’ worst enemies are rats. Tuataras once inhabited the New Zealand mainland as well as offshore islands. But when the first humans arrived from Polynesia, they brought rats and other animals that devoured tuatara eggs and hatchlings. The situation was so dire that the New Zealand government fully protected tuataras in 1895. Despite the protection, tuataras were extinct on the mainland and confined to around 30 offshore islands until the first mainland release of tuataras into a sanctuary in 2005. Three years later, a tuatara nest was uncovered, thought to be the first case of a tuatara successfully breeding on the New Zealand mainland in over 200 years. Along with captive breeding and release programs, attempts to eradicate rats from offshore islands have also met with success and allowed tuatara populations to rebound.

Science facts: Firenados are a thing that happens

Wanna discover amazing science facts: Firenados are a thing that happens. Keep reading on to know

1. Firenados are a thing that happens.

Firenados are fairly self-explanatory and completely terrifying. They are tornadoes that are full of raging hot flames. They occur during wildfires, which, due to all that rising hot air, create their own massive winds, which can pull more oxygen into the fire, making them stronger as they pull the flames high into the sky.

2. The tallest known cliff in the Solar System is on Uranus’ tiny moon Miranda.


Uranus’ tiny moon Miranda has a cliff named named Verona Rupes that is estimated to be up to 10 times the depth of the Grand Canyon. Due to Miranda’s low gravity and the height of the cliff, it would take a full 12 minutes to jump off of this thing. It remains unclear why such a small object would have such a ragged surface.

3. There was a time when dragonflies the size of seagulls terrorized the Earth.


These bad boys were named Meganeura and were closely related to living dragonflies. They lived around 300 million years ago and preyed on smaller insects. How and why such large insects could develop at that time is still an open question.

4. All the planets of the Solar System could theoretically fit in the space between Earth and the Moon.


The average distance between the Earth and the Moon is 239,200 miles. The total distance covered by the the diameter of all the planets stacked next to each other is 233,865 miles. Plenty of room to spare! This is one of the most amazing facts ever.

5. An entirely new system in the human body was discovered thanks to weed.


It’s called the endocannabinoid system, and it’s in yo brain. It just so happens that the chemicals in pot target this system exclusively. In fact, it was our understanding of those plant-based chemicals that led to the discovery of the endocannabinoid system in the mid-1990s. It plays a role in pain, learning, appetite, and a whole variety of other things, too.

6. Male koalas have two penises and female koalas have three vaginas.

The males of most koala species have a bifurcated penis — essentially that means they have two penises. A female koala has two “lateral vaginas” which transport semen, and a third “medial” vagina, which their young travel through during birth.

7. Russia is bigger than Pluto.


When it comes to surface area, Russia takes up a whopping 6.6 million square miles. Pluto, on the other hand, has a surface area of only 6.4 million square miles.

Science facts: What you need to know about Neptune planet

Enjoy our rich source of science facts that can help you widen your knowledge. And now it's the time for Neptune facts. Neptune is the eighth planet from the Sun making it the most distant in the solar system. This gas giantplanet may have formed much closer to the Sun in early solar system history before migrating to its present position.


Fact #1

Neptune is the most distant planet in the solar system.

Fact #2

Neptune was originally called Le Verrier’s Planet (named after the man who discovered it, Urbain Le Verrier. There were a number of suggestions about what to call this planet. And in the end, the man who discovered this planet chose the name Neptune.

Fact #3

Neptune has 13 known moons. The largest moon is Triton, one of the coldest places known within our Solar System. The temperature on the surface of this moon can dip down to an amazing -235 degree Celsius.

Fact #4

A Neptunian year lasts for 164.79 Earth years. Because of Neptune distance from the Sun, It takes 164.79 Earth years to orbit the Sun once. Neptune has a similar tilt on its axis as Earth does. This means that it has similar seasons as our does, only they last much, much longer. An average summer on Neptune would last for 41 years. This might be one of the most amazing facts in total that can better your knowledge.

Fact #5

Each day on Neptune lasts for around 16 hours, and 6.5 minutes.


Fact #6

The strongest winds that have ever been recorded in the Solar System have come from Neptune, with speeds at 2,000 kilometers per hour.

Fact #7

Some people believe that Pluto was once a moon of Neptune that broke away from Neptune’s gravitational pull.

Fact #8

Like Saturn, Neptune has three rings orbiting the planet. Two are fairly thick, while the third is very faint ring. These rings are smaller than the rings of Saturn and are made of dust. Do you believe that this is the truth, not just jokes for fun?


Fact #9

Although Neptune is smaller in diameter than Uranus, it has a greater mass. Neptune’s mass is 17 times greater than that of Earth’s, whilst Uranus is only 14.5 times greater.

Do you want to check out weird animal festivel that can blow your mind:

Monkey Buffet Festival, Thailand


Each fall in Lopburi, a city located in southern Thailand, thousands of macaques are invited to an impressive culinary feast.

The monkeys are treated to an amazing feast of fruits, vegetables and soft drinks at the city's annual Monkey Buffet Festival at Prang Sam Yot, an ancient temple where the macaques like to hang out, reports the Los Angeles Times.

In addition to being a massive special meal for the macaques, the festival is quite the draw for tourists who flock to Lopburi to watch the monkeys gorge on soda and produce.

Pushkar Camel Fair, India

The Pushkar Camel Fair in Rajasthan, India was originally created as a place for local people to sell and trade livestock, and now it becomes a very popular event that attracts more than 11,000 camels, horses and cattle, as well as about 400,000 people who go to witness the colorful spectacle. Some groups of animals, herders and traders need to travel for 3 weeks to get to the fair. 

funny images on weird festival

Together with camel and horse sales and trades, there are also camel races, camel cart rides and camel competitions. Non-camel events are turban and mustache contests, as well as concerts and cultural events. Souvenirs include camel dung paper and notebooks, camel wool shawls and camel cheeses, cakes and cheesecakes, all made with camel milk.

Alaska Bald Eagle Festival, Alaska, the U.S.

Each year about mid-November, several thousand bald eagles descend on Chilkat Bald Eagle Preserve in Haines, Alaska, to feed on late-running salmon. The American Bald Eagle Foundation holds an annual festival that attracts people from all around the world to the 48,000-acre preserve to see the majestic birds.

In addition to eagle-viewing opportunities, the Alaska Bald Eagle Festival also has presentations on eagle behavior, birding tours and photography workshops, as well as a craft bazaar and Alaskan wildlife and artisan workshops.

Swiss cow parades, Switzerland

Each fall in various towns throughout Switzerland, cows are dressed with flowers, ribbons, flags and other fancy regalia as they are herded down from their mountain pastures and paraded back to their homes in a show of respect for their work.

Herdsmen sometimes also dress in traditional garb and the villagers line up and cheer as they watch the colorful spectacle and the melodious ring of the cow bells. Called Alpabzugs, Alpabfahrts, Alp Processions or Cow Parades, the annual celebrations are often accompanied by festivals, folk singing and dancing, and dairy and produce markets. Similar parades are also held in various towns throughout Austria and Germany (Source: factoflife).

Diwali Festival of Dogs, India and Nepal

Dogs in India are honored each fall as part of the Hindu festival of Diwali or Festival of Lights. Specifically in Nepal, one day of the celebration is devoted to dogs, called Kukur Tihar. On that day, pet dogs and strays alike are given treats, decorated with marigold flower garlands and are smeared with vermillion on their heads as a sign of their sacredness.

It's customary during the celebration for people to offer blessings to their dogs which are, according to Hindu tradition, the messenger of Yamaraj, the god of death and the guardians of the gates of the afterlife.

Human death and its reason

Keep reading to know the answer for interesting science facts on human death. Let's jump right in!

Image result for why human die

Organisms grow old because nature doesn't need them any more. If the purpose of life is to procreate and replicate successfully - this is the logic of the so-called selfish gene theory - then it helps to stay healthy long enough to generate children and provide them with food. Immortality arrives with your offspring, and is only guaranteed when all your children also have children. weird facts

Different species place their bets on life's roulette wheel in different ways. If you're an oyster or a salmon or a fruit fly, the process is over quickly enough: lay a huge number of eggs somewhere safely and die. If you're a tigress or a dolphin, the process isn't so simple: you have to bear the young, rear them, provide food on a daily basis and guide them to maturity. If you are a human, you get a little bit of extra grace: you can be useful to your grandchildren, so there is some evolutionary pressure to stay alive that little bit longer. And then there's the bonus: being human, you have all the resources of society and technology to keep you safe from predators and healthy and active for just a bit longer.

But sooner or later, the biological clock begins to run down. Cells that had faithfully renewed themselves begin to fail. A heart that pounded away in perfect synchrony begins to run down after a couple of billion beats. Joints that withstood rugby, football, rock'n'roll and the gymnasium treadmill start to creak. Skin that bloomed in the spring sunshine begins to weather and flake in life's autumn. Brains shrink, spines curve, eyes begin to fail, hearing goes, organs become cancerous, bones begin to crumble and memory perishes.


Ageing seems inevitable but, for some scientists, it isn't obvious why this process is inexorable. Human chromosomes seem to arrive with their own lifespan timing devices called telomeres, but precisely why and how telomeres are linked to ageing is still not understood. There are genes that seem to to dictate survival rates in fruit flies, nematode worms and mice, and these genes almost certainly exist in humans, but what works in an insect or even another mammal may not be much help to a human anxious to hang around a bit longer. Even so, in the last half of the 20th century, life expectancies were increasing everywhere in the developed and developing world, wherever there was appropriate sanitation, nutrition, education and medical care; and small groups of scientists had begun to ask whether life could be extended indefinitely.

Ocean color and the explaination

Do you know about ocean color and the explaination for this amazing science facts? See the best answer as belows:



"The ocean looks blue because red, orange and yellow (long wavelength light) are absorbed more strongly by water than is blue (short wavelength light). So when white light from the sun enters the ocean, it is mostly the blue that gets returned. Same reason the sky is blue."
In other words, the color of the ocean and the color of the sky are related but occur independently of each other: in both cases, the preferential absorption of long-wavelength (reddish) light gives rise to the blue. Note that this effect only works if the water is very pure; if the water is full of mud, algae or other impurities, the light scattered off these impurities will overwhelm the water's natural blueness.
Gross then asks, "So why are sunsets orange?" Several people to wrote in to correct or clarify that comment.
Perhaps the most helpful response came from Michael Kruger of the department of physics at the University of Missouri. He sent the following reaction:
"The answer to why the sky is blue isn't quite correct although there are many funny pics to prove it. The sky is blue not because the atmosphere absorbs the other colors, but because the atmosphere tends to scatter shorter wavelength (blue) light to a greater extent than longer wavelength (red) light. Blue light from the sun is scattered every which way, much more so than the other colors, so when you look up at the daytime sky you see blue no matter where you look. This scattering is called 'Rayleigh scattering'; the amount of scattering goes as the frequency of the light to the 4th power. By the way, this effect is most prevalent when the particles that do the scattering are smaller than the wavelength of light, as is the case for the nitrogen and oxygen molecules in the atmosphere.
"Now we are in a position to figure out why sunsets are reddish! When the sun is setting, the light that reaches you has had to go through lots more atmosphere than when the sun is overhead, hence the only color light that is not scattered away is the long wavelength light, the red.
"We can also answer why clouds, milk, powdered sugar and salt are white. The particles in these materials that are responsible for scattering the light are larger than the wavelength of light. Consequently, all colors of light are scattered by more or less the same amount. Much of the scattering in milk is due to the lipids (fat). If you take out the fat, the milk will not scatter as much light; that is probably why skim milk looks the way it does.

Real Fight Of Lion And Tiger

If there is a  real fight of Lion and tiger, which would win? Let's see:

Well, let’s talk size first. Tigers are heavier, weighing up to 800 pounds to the lion’s 550. But the two cats aren’t so different in size. Here, their profiles are superimposed:
For more: tiger facts                         


You might remember from high school health class that muscle weighs more than fat, which helps explain the tiger’s extra pounds. So it seems that the tiger would have a physical advantage over the lion.

But it turns out that we have some historical data to add to this conjecture, too. In ancient Rome, the tiger-lion face-off wasn’t uncommon. In 1959, a reader asked the Spokesman-Review this question, and the paper, in turn, asked William Bridges, the curator of publications at the Bronx Zoo. He told them that “back in the day of the Roman Coliseum, the smart money usually backed the tiger.” While we don’t have any great descriptions of the outcomes, ancient paintings of the event usually showed the tiger winning. And in the late 1800′s, the Gaekwad of Baroda, an Indian ruler, arranged a fight between the two beasts. Before the fight began, those running the bettor set the odds at 1 to 37,000 that the tiger would win. It did, and the Gaekwad lost 37,000 rupees.

And in 2011, a tiger killed a lion with a single paw swipe in a run in at Ankara Zoo in Turkey. The tiger apparently found a gap in the fence, and made its way into the lion’s enclosure. When they met, the tiger severed the lion’s jugular vein in just one stroke. Craig Saffoe, a biologist at the Smithsonian Zoo, also generally favored the tiger, telling LiveScience, “What I’ve seen from tigers, they seem to be more aggressive; they go for the throat, go for the kill. Whereas the lions are more, ‘I will just pound you and play with you.’”



But fighting in an arena, and even in a zoo, is quite different than fighting in the wild. If a tiger were to meet a lion without cages or screaming fans, what would happen? That’s actually a question that some conservationists are having to answer right now. There’s a plan to move some Asiatic lions to from the Gir forest to Kuno Palpur, where there are tigers. The University of Minessota’s Lion Research Center says that the plan has been delayed for fear that the native tigers would kill the lions. But in the wild, they say, tigers and lions fight quite differently:

Coalitions of male lions usually fight as a group against territorial rivals, so a tiger may have an advantage in a one-on-one encounter, since this is the typical mode of combat for a tiger. However, a lion coalition of 2–3 males would have a clear advantage over a lone tiger. A group of 2–4 female lions would have a similar advantage over a lone tigress.

They conclude that while one on one, a tiger would certainly best a lion, in the wild the lion pride could hold their own against the solitary tiger.

Daily Requirement of Vitamin C

All background information about vitamin C will appear in this writing, just keep reading to know

Image result for why vitamins are necessary in our diet

Vitamin C

It is found in sufficient amount in the fresh fruits, animal liver, milk, green vegetables, blackcurrant, guava, all the citrus fruits (like orange, amla, lemon, grapefruit), broccoli, strawberries, papaya, cauliflower, pineapple, cantaloupe, watermelon, garlic, cabbage, mango, grape, banana, onion, carrot, apple, beetroot, pear, cucumber and etc. However, it gets destroyed over high temperatures while boiling the food.

Vitamins C is required by the body for the production of collagen which makes the skin healthy and glowing, hair strong and long, teeth and gums healthy, blood vessels and joints cartilage powerful and etc. It also acts as an antioxidant, prevents the body from tissue damage (free radicals), enhances the iron absorption in the intestines and lowers the risk of cancer.

It enhances the wound healing process and plays a significant role in red blood cells formation. It also enhances the level of brain chemical called as noradrenaline (an important neurotransmitter) and improves the alertness and concentration power.

Deficiency of Vitamin C

Its deficiency causes scurvy and lower level may lead to the variety of heart diseases, lung problems, poor wound healing, strokes, cancer, bleeding gums, skin discoloration, weak immune functioning, frequent cold and other infections.

Daily Requirement of Vitamin C for Different Age Group

Daily requirement of this vitamin depends on the age and sex of the person. I have mentioned below the daily requirement of the vitamin C for different age group people:
Infants between 0-6 months of age require 40 mg/day.
Infants between 6-12 months of age require 50 mg/day.
Children between 1-4 years of age require 15 mg /day.
Children between 4-9 years of age require 25 mg /day.
Males and females between 9-14 years of age require 45 mg /day.
Males between 14-19 years of age require 75 mg /day.
Males above 19 years of age require 90 mg /day.
Females between 14-19 years of age require 65 mg /day.
Females above 19 years of age require 75 mg /day.
Pregnant women from 18 and above years of age require 80-85 mg /day.
Lactating women from 18 and above years of age require 115-120 mg /day.

Giraffes - Diet and offspring

Giraffes are the world's tallest mammals, thanks to their towering legs and long necks. As we know, a giraffe baby legs alone are taller than many humans.

Diet

Giraffes are herbivores, which means they eat only plants. Their long necks allow them to reach leaves, buds and branches high up in mimosa and acacia trees. They can eat hundreds of pounds of leaves per week, according to National Geographic.

Though these animals eat a lot, giraffes can go without drinking for weeks at a time. They get most of their moisture from the vegetation they eat.

Offspring

As in cattle, female giraffes are called cows, while the males are called bulls. After mating, the cow will have a gestation period of around 14 months. During birth, the calf will drop to the ground, since mother giraffes give birth standing up. The fall can be as far as 5 feet (1.5 m), according to National Geographic.

New calves are quite large, at 6 feet tall (1.8 m), 100 to 150 lbs. (45 to 68 kg), according to the San Diego Zoo. They are also agile. At just an hour after birth, they can stand up and walk around. 

Giraffe mothers often take turns watching over the calves. Sometimes, though, the mother giraffe will leave the calf by itself. When this happens, the infant will lie down and wait for its mother to return.

At 3 to 6 years old, calves are fully mature. The animals can live up to 20 years.

How much vitamin C should we take?

Whether for the purpose of keep healthy or loose weight, play an important role in our daily life. Learn more about how to get enough vitamin c to succeed at your goals below!

Kết quả hình ảnh cho vitamin c can help lose weight

Vitamin C, also known as ascorbic acid or L-ascorbate, is an essential vitamin to the human body. It could very well be one of the safest and most important vitamins you could take on a daily basis. Vitamin C is most known as the first thing people go for whenever they have a cold. It is a water-soluble vitamin that is necessary for normal growth and development. Since it is water soluble, extra amounts that the body doesn't use leaves the body through urine within 24 hours.

Now that we know you need vitamin C and why, we have to figure out how much you should take. The Food and Drug Administration set their guidelines for how much a person should take for general health. These are the FDA recommendations for each age group and gender.

Infants And Children

0 - 6 months: 40 milligrams/day (mg/day)
7 - 12 months: 50 mg/day
1 - 3 years: 15 mg/day
4 - 8 years: 25 mg/day
9 - 13 years: 45 mg/day

Adolescents

Girls 14 - 18 years: 65 mg/day
Boys 14 - 18 years: 75 mg/day

Adults

Men age 19 and older: 90 mg/day
Women age 19 year and older: 75 mg/day

Now these guidelines aren't designed for athletes. Those folks that are active obviously need more C than the non-active person would. It is believed that active people can benefit from taking anywhere from 500 milligrams to as much as 3,000 mg a day, depending on the person's daily activity level. If you are sick, you may need as much as eight grams a day for the duration of your illness.

The Tale of the Tiger

Recognizing a tiger at the zoo is easy. But in their natural habitat, tigers are really hard to find. That’s because their unique orange, black and white stripe pattern helps them blend into the forests and grassy areas where they live and hunt.
Tigers are carnivores. They are quiet, patient hunters with large powerful paws and teeth to help them catch and eat their prey. Some of their favorite meals include pigs, deer, rhinoceroses, and even small elephants.
Tigers hunt for their food, but they are also hunted by humans for their valuable fur and body parts. Because of this, tiger researches think there may only be 3,500 tigers left in the world. This makes them an endangered species.

Also see elephant facts

Range

Historic tiger range ran from Turkey through South and Southeast Asia to the far eastern shores of the continent. Today, they are only found in South and Southeast Asia, China and the Russian Far East.

Behavior

Tigers occupy a variety of habitats from tropical forests, evergreen forests, woodlands and mangrove swamps to grasslands,savannah and rocky country. They are mostly nocturnal (more active at night) and are ambush predators that rely on the camouflage their stripes provide. Tigers use their body weight to knock prey to the ground and kills with a bite to the neck. They are also very good swimmers and have been known to kill prey while swimming.
Tigers essentially live solitary lives, except during mating season and when females bear young. They are usually fiercely territorial and have and mark their large home ranges.

Reproduction

Mating Season: In tropical climates, mostly from around November to April; during the winter months in temperate regions.
Gestation: 103 days.
Litter size: 3-4 cubs.
Cubs follow their mother out of the den at around 8 weeks and become independent at around 18 months of age. They leave their mothers at about 2 ½ years. Mothers guard their young from wandering males that may kill the cubs to make the female receptive to mating.

Many interesting cockroach facts

Have you known about some following interesting cockroach facts before:

1. Cockroach Eating Contests

If a cockroach is beheaded it will never die because of the loss of its head. The only thing killing it will be the thirst as it can’t drink water without a head. Their respiratory system has nothing to do with the mouth as they can breathe through little pores in their body.
Cockroach Eating Contests


The Six Flags Great America theme park in Chicago came up with a very gag-worthy promotion for Halloween back in 2008. They offered park passes to the winner of a contest to eat the most live cockroaches in the space of five minutes. A doctor advised people against taking part because of the microorganisms that live inside the insects. Nevertheless, the parkresurrected the contest in 2011, citing “popular demand.”

The true risk of this sort of contest was shown in Florida. A competitor named Edward Archbold died shortly after a pet shop held a roach-eating competition with a python as a prize. He suffocated after choking on bits of cockroach that got lodged in his throat. Six Flags decided to call off their contest following the death.

2. A Cockroach Can Cause Many Diseases

Cockroaches love to live in filth and dirty places and in these interesting cockroach facts; this fact is about their contaminating abilities. A cockroach is usually completely enveloped in filth. They can move as fast as 3 miles per hour. It will take only a few minutes for a single cockroach to fully contaminate a house. That’s why they can cause many dangerous diseases among humans.


3. Cockroach Facts: German Cockroaches

German cockroaches are considered the most dangerous than others cockroaches. They are the most common type found in almost every nation. They can cause illness, allergy and in some severe cases breathing problems in humans. They can become fully adult within a time span of 36 days.


4. Cockroaches Like to Live in Small, Closed Places

There are many interesting cockroach facts and this fact will tell you about their habit of living in small and closed places. All the cockroaches are thigmotropic i.e. they are sensitive to touch from all sides. They like to crawl in small and tight places to fit in. They really seem to enjoy a place closed from all sides. A pregnant mother cockroach can even manage to fit in a place not wider than two vertically combined coins.


5. Cockroach Facts: Cockroaches Can’t Live Without Water

They are cold blooded and can survive for a month without any food. They usually don’t remain without food for that much long as they can eat anything in their way. Their real problem is the shortage of water. No water for a week can kill them. So primarily they need water to survive not the food.


6. Cockroaches are used as Food in Some Countries

In these cockroach facts, this fact is probably the weirdest of all. Even though they are hated by most people especially women but still there are places in the world where they are served as food. Countries like Ghana, Thailand, Mexico, China and even in some places of America they are served as food. In the November of 2012 a cockroach eating contest was held. But unfortunately the winner of the contest died soon after the competition. He choked to death on the small pieces of roaches in his throat.
