Our skin is a very important part of our bodies that we often take for granted. Without it we’d fall apart, be covered with bacteria-caused infection and our organs would be severely burned by the sun’s rays. We wouldn’t be aware of the dangers in our environment that could burn, freeze or puncture our other organs. We wouldn’t be able to cool off when we get overheated or warm ourselves when we feel a chill. If our skin didn’t grow as our body grows, we’d explode like an over inflated balloons.
