Friday Fun: Five Gross and Goofy Body Facts

1. Believe it or not, you’ll walk about 115,000 miles (185,075 kilometers) in your life. If all that trekking and trudging were in a straight line, you could circle the equator four and a half times!

2. You usually breathe about twelve times a minute. And each breath delivers about 2 cups (0.5 l) of air to your lungs. That works out to 96 gallons (363 l) per hour and 2,300 gallons (8,706 l) per day. That’s a lot of air!

3. Like the water slowly dripping out of a leaky faucet, your body is constantly cranking out a fresh supply of tears. They’re made inside tear glands, small sacs located above your eyes. Most days about 1/3 of a teaspoon (1.7 milliliters) of new tears trickle into each eye.
4. Go just ten seconds without oxygen, and you’ll faint. After five minutes with no air, your brain could be permanently damaged. And if you stopped breathing for ten minutes, you’d probably die.

5. When police find human bones, scientists can calculate the person’s height and weight. They can also tell whether the bones came from a male or a female and how old the person was. Sometimes they can even figure out where the person lived and what kind of job he or she had.
