Trivias on Human Body

Thanks to Funology.com. I've found these following trivias really interesting.

• The dust on rugs and your furniture is not only dirt. It’s mostly made of dead skin cells. Everybody loses millions of skin cells every day which fall on the floor and get kicked up to land on all the surfaces in a room. You could say, "That’s me all over."
  
• The width of your armspan stretched out is the length of your whole body.
  
• You blink your eyes over 10,000,000 a year.
  
• The longest bout of hiccups lasted 69 years!
  
• Your fingernails grow almost four times as fast as your toenails.
  
• Your tongue has 3,000 taste buds.
  
• A human's small intestine is 6 meters long.
  
• Can you feel the pulse in your wrist? For humans the normal pulse is 70 heartbeats per minute. Elephants have a slower pulse of 27 and for a canary it is 1000!
  
• In one day your heart beats 100,000 times.
  
• Coughing can cause air to move through your windpipe faster than the speed of sound — over a thousand feet per second!
  
• Germs only cause disease, right? But a common bacterium, E. Coli, found in the intestine helps us digest green vegetables and beans (also making gases – pew!). These same bacteria also make vitamin K, which causes blood to clot. If we didn’t have these germs we would bleed to death whenever we got a small cut!
