20 Awsome facts - 1
1.Cracking your knuckles does not actually hurt your bones or cause arthritis. The sound you hear is just gas bubbles bursting.
Cracking your knuckles (or any of your joints) can have therapeutic benefits. When you crack one of your joints you are pulling the bones that are connected at the joint apart from each other. This process stimulates your tendons, relaxes your muscles, and loosens your joints. Chiropractors do this for spinal joints when your back is sore and stiff, but you can do this on your own for your knuckles, toes, knees, neck, etc.
Unfortunately, there can be too much of a good thing. Cracking your knuckles will never lead to arthritis (despite what your mom keeps telling you), but scientists have discovered that it can cause tissue damage in the affected joints. Knuckle-cracking pulls your finger bones apart which stretches your ligaments. Too much stretching of your ligaments will cause damage to your fingers akin to the arm injuries sustained by a baseball pitcher who throws too many pitches. In addition to making your hand really sore, this ligament damage can also result in reduced grip strength.
How does this work? Your joints, the places in your body where you can bend, are where your bones intersect and are held together by ligaments. These joints are surrounded by a liquid called synovial fluid. When you stretch your ligaments by pulling the bones apart to crack your knuckles a gas in the synovial fluid escapes and turns into a bubble. This process is called cavitation. Cavitation ends when the bubble eventually bursts, producing that popping sound we know and love. After that, your joints won't be able to crack for another 25-30 minutes while the gas gets reabsorbed into the synovial fluid.
2.If you touch your tongue while yawning, it can stop the yawn.
3.Women speak about 7,000 words a day. The average man averages just over 2,000.
4.When you laugh while being tickled, what you are experiencing is actually a form of panic.
When a person is tickled, the response is actually a form of panic, as the brain interprets the tickling sensation as produced by spiders or other creepy crawlies on your skin - the uncontrollable laughter is a response to panic.
5.Yawning is contagious - even thinking about yawning is enough. After reading this fact, there is a 50% chance you will yawn.
Research shows that 11-week-old fetuses yawn. Yawns become contagious to people between the first and second years of life. When one person in a group yawns, over half of the people in the group will yawn within 5 minutes, and the rest will at least be tempted to yawn. Even animals yawn when they see another animal yawn. The average duration of a yawn is about 6 seconds, and guys yawn for longer than girls.
6.The total weight of all the ants on Earth is about the same as the weight of all the humans on earth.
Ants also outnumber us a million to one! They also can lift weight twice their size! If they ever wanted to turn on us, they could just pick us all up and throw us in the ocean.
7.A Rubik's cube has 43,252,003,274,489,856,000 possible configurations.
With 6 colored sides, 21 pieces and 54 outer surfaces, there's a combined total of over 43 quintillion different possible configurations. To put that into perspective: if you turned the Rubik's cube once every second it would take you 1400 trillion years to finish to go through all the configurations. If you had started this project during the Big Bang, you still wouldn't be done yet.
8.In Japan they have square watermelons.
They get square watermelons by growing them inside of square glass cases. That way they can fit easily into a refrigerator, and you can stack things on them. Square watermelons are expensive though (10,000 yen or about $82). Compare that to regular round watermelons which cost about $15-20 in Japan.
9.'Dreamt' is the ONLY WORD in the entire English language that ends in the letters 'mt'
10. 45% of Americans are unaware that the sun is a star.
Only 55% of all Americans know that the sun is a star.
11.Breathing the air in Mumbai, India for just ONE DAY, is equivalent to smoking 2.5 packs of cigarettes.
12.Like fingerprints, everybody's tongue print is different.
13.Your earlobes line up with your nipples.
14.Men have nipples because, as an embryo, everyone is a female until the Y chromosome kicks in.
After conception, the human embryo develops as a female. Only after 6-8 weeks does the Y chromosome kick in and the fetus begins developing male characteristics. By this point breast tissue, milk ducts and nipples have already formed. This happens in all mammals, the only exception being stallions, who do not posses nipples.
Generally evolution will only weed out a characteristic if it proves harmful to the creature, and of course, although having nipples provides no benefit to a man it has no ill effect either. Darwin (and others) wondered if at some point in the very distant past the males of a species from which we are descended suckled their young.
15.Justin Bieber can solve a Rubik's Cube in less than 2 minutes.
16.Ever heard of a Cryovolcano? It's a volcano that shoots out ICE rather than lava.
Cryovolcanoes only exist in outer space. They can be found on icy moons.
17.The Moon is moving an inch away from Earth EVERY YEAR. Some day, we won't have solar eclipses anymore.
Who's to blame? The ocean. The Earth and the Moon constantly interact through gravitational forces. This push-and-pull through space creates tidal forces on Earth, which, in turn, pulls back on the Moon, making bulges on the Moon's surface.
The result: Tidal forces are slowly warping the moon's shape, from a sphere to an egg shape, the Moon's orbit is speeding up, and the gravitational pull between the Earth and the moon are weakening. Johannes Kepler observed in the 1600s that as the Moon's orbit speeds up, the Moon will slowly move away from Earth. These gravitational forces are also slowing down the Earth, making our days longer.
Millions of years in the future, the Moon will be so far away from the Earth that we won't be able to have solar eclipses!
18.Put two straws in your mouth: one inside a drink and one outside it. You won't be able to drink through either straw. Try it!
19.The largest number of children ever born to one woman was 69!
The largest number of children born to one woman is recorded at 69.
More info: According to the Guiness Book of World Records, from 1725-1765, a Russian peasant woman gave birth 27 times to 16 sets of twins, 7 sets of triplets, and 4 sets of quadruplets.
20.If you type "James Bond" into Google Translate and have it translated to Standard Chinese, it will translate to "007".
