Here is an amusement for you from Time Goes By. It is called The Amazing Human Body and I have no idea if these facts are true. But just go with it and you'll be rewarded with a good laugh at the end):
It takes your food seven seconds to get from your mouth to your stomach.
One human hair can support 6.6 pounds.
The average man's penis is two times the length of his thumb.
Human thighbones are stronger than concrete.
A woman's heart beats faster than a man's.
There are about one trillion bacteria on each of your feet.
Women blink twice as often as men.
The average person's skin weighs twice as much as their brain.
Your body uses 300 muscles to balance itself when you are standing still.
If saliva cannot dissolve something, you cannot taste it.
Your body is made of about 7 octillion atoms (that’s 7,000,000,000,000,000,000,000,000,000 atoms).
There are 37 trillion cells in your body.
Stomach acid can dissolve metal.
Your skin’s outer layer sheds every 2-4 weeks, amounting to roughly 0.7 kg of dead skin in a year.
Cells in the inner lens of the eye, muscle cells of the heart, and the neurons of the cerebral cortex are the only cells that will be with you your entire life.
If you were to spread out all the wrinkles in your brain, it would be about the size of a pillowcase.
There are a trillion nerves powering your memory. Studies have shown that after viewing 2,500 images for only 3 seconds, participants could recall if they had seen the images with 92 percent accuracy.
You spend 10 percent of the day blinking.
Women will be finished reading this by now.
Men are still busy checking their thumbs.
