Yes we humans have skin that is water proof and protects us from the environment. In fact, I believe our skin is the largest organ of the human body. Our skin is also a great filtration system in helping to remove toxins from our body and to maintain our temperature. I am very much for the science and medical science to be sure. So, I agree with you.
But to put up front a prunie little finger and make it the single point of the topic is well funny and if that is the single point of the conversation seems like a waste of money.
