Answer 1

Ok, think about it.  Does your skin prevent germs from getting inside you?
Does your skin prevent water from leaving the body too quickly?  Does your skin protect your insides from getting damaged when you fall?  Do you put food on your skin to absorb nutrients, or do you put food in your mouth like a normal person?
