Female Speaker: Here are some interesting facts about the human body. Did you know that that length from your wrist to your elbow is about the same length as your foot. Well, let's put that to the test. Yeah, about 10.5 inches and my foot about 10.5 inches, so let's see if it works, yep it's about right. The outside of your eye is called the cornea. Now the cornea cells are the only cells in the body that don't need to get their oxygen through the blood. They can actually get the oxygen that they need from the air, so that's why when you use contacts too frequently or sleep in them its bad for your eyes because there not getting the oxygen that they need. We all know with this is right. Well if you saw somebody trying to use this on their hair, you may think they are little weird, huh well they may not be as weird as you might think because your hair is made out of the same material as your fingernails.
Did you know that it takes 72 muscles to produce human speech. You may notice that you have to cut your fingernails more often than your toe nails. Well, that's because the longer the finger, the faster it grows, so the middle finger is going to grow the fastest and the thumb is going to grow the slowest. Your toes are about a third of the size of your fingers, so that means that you have to cut your fingernails three times with often as your toe nails. The muscle that controls your eyelid is the fastest muscle in your entire body. It allows you to blink about 5 times a second and about 15,000 times a day. Another interesting thing is that women blink about twice as many times as men. Well, you probably already know that a yard is 3 feet but, who came up with the yard. Well that was King Henry I in the 12th century he came up with the standardized strength of the yard. It was the distance from his nose to his thumb. When you see pictures of bones in magazines or when you see them at a museum, they tend to be white so you might think that the bones in the body are white but that's not true. The living bones in the human body range from colors of beige to a light brown. The reason why they are white in museums and in pictures is because they take the bones and they boil them and then they clean them, so it bleaches them white.
