Did you know the following?


1. Humans shed about 600,000 particles of skin every hour. That works out to about 1.5 pounds each year, so the average person will lose around 105 pounds of skin by age 70.
   
2. An adult has fewer bones than a baby. We start off life with 350 bones, but because bones fuse together during growth, we end up with only 206 as adults.
   
3. Did you know that you get a new stomach lining every three to four days? If you didn't, the strong acids your stomach uses to digest food would also digest your stomach.
   
4. Your nose is not as sensitive as a dog's, but it can remember 50,000 different scents.
   
5. Every square inch of skin on the human body has about 32 million bacteria on it, but fortunately, the vast majority of them are harmless.
   
6. The source of smelly feet, like smelly armpits, is sweat. And people sweat buckets from their feet. A pair of feet have 500,000 sweat glands and can produce more than a pint of sweat a day.
   
7. Blood has a long road to travel: Laid end to end, there are about 60,000 miles of blood vessels in the human body. And the hard-working heart pumps about 2,000 gallons of blood through those vessels every day.
   
8. In a lifetime, the average person produces about 25,000 quarts of saliva- enough to fill two swimming pools!
   
9. Sound of a snore can seem deafening. While snores average around 60 decibels, the noise level of normal speech, they can reach more than 80 decibels. Eighty decibels is as loud as the sound of a pneumatic drill breaking up concrete.
   
10. The human head is one-quarter of our total length at birth but only one-eighth of our total length by the time we reach adulthood.
