Tongue PrintDon't stick out your tongue if you want to hide your identity. Similar to fingerprints, everyone also has a unique tongue print!
Shedding Your pet isn't the only one in the house with a shedding problem. 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.
Bone CountAn 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.
New StomachDid 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.
Scent RememberingYour nose is not as sensitive as a dog's, but it can remember 50,000 different scents.
Sneeze SpeedThe air from a human sneeze can travel at speeds of 100 miles per hour or more -- another good reason to cover your nose and mouth when you sneeze -- or duck when you hear one coming your way.
Saliva QuantityYou may not want to swim in your spit, but if you saved it all up, you could. In a lifetime, the average person produces about 25,000 quarts of saliva -- enough to fill two swimming pools!
Head Weight
No wonder babies have such a hard time holding up their heads: 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.
