If they are placed together, twelve thousand cells will cover one square inch. SWEAT AND BREATH: Your body possesses twenty million sweat glands and your brain has nine hundred million cells. To provide oxygen to your blood, your lungs contain forty million sacks and weigh two pounds. The lungs pump oxygen one thousand times in twenty-four hours in these sacks. Your windpipe contains 300 million cells that are 1/100th of an inch in diameter. The eye-lid holds 5 million cells and each cell has a nerve. Your ears contain ten thousand cells. MILK: If one pound of milk is left uncovered for 24 hours, it will develop 2 billion bacteria. People often use milk left in that state. When your body is so full of germs and bacteria how can you remain healthy? One germ of tuberculosis is only 200th of an inch in diameter and one thousand germs can be collected on a pinhead. One germ can reproduce two hundred thousand germs in three days. HAIR: The hairs on the chin of a young man grow about six inches in a year. If some of these hairs did not fall off naturally, then one could grow a beard 30 feet long in seventy years. • • •
