The skin is your body’s largest sensory organ. It keeps you in touch with the world. The skin of an average adult male weighs nine pounds. It covers about 20 square feet. That’s as much space as the floor of a very large closet!
Skin keeps fluids in your body and infections out of it. It lets you know if you are too hot or too cold. It alerts you to danger. And it lets you experience the affection of loved ones. People have survived without the use of eyes, ears, nose, or tongue. But we can’t live without our skin.
