The amazing human body

Consider this:

• If you took your small intestine out, it would stretch approximately 20-22 feet.
• You've got over 600 muscles.
• You've got over 45 miles of nerves in your skin.
• You've got over 60,000 miles of blood vessels (with every square inch of your skin containing about 20 blood vessels)
• You're carrying around 300 bones if you're a baby; only 206 if you're grown.
• An average human scalp contains around 100,000 hairs -- more if you're a blonde.
• You've got about 32 million bacteria on each square inch of your skin.
• You're losing approximately 600,000 particles of skin every hour -- that averages out to about 1.7 pounds per year, or 105 pounds by the time you're 70 years old. Fortunately, you grow an entire new set of skin cells about every 27 days, which means that you will have grown about 1,000 new skins during your lifetime, assuming you make it to 70ish.
• You will produce around 25,000 quarts of spit during your lifetime -- enough to fill two swimming pools.
• Every minute 300,000,000 of your cells die.
• Your left lung is smaller than your right lung (to make room for your heart which will beat approximately 2.5 billion times if you make it to age 70).
• Fortunately, you've got, on average, around 25 sq. feet of skin to hold all this stuff together. Otherwise, where would you put it all?

And here's something important you should know: it takes 43 muscles to frown, but it only takes 17 to smile.
