Skin Documentary Tidbits

Watched an hour-long National Geographic documentary last night about the evolution of skin and how it defines people. Here are few interesting facts from the documentary:

* 5 million hair follicles cover our bodies

* The brain and skin are deeply connected. The first sense to develop in the womb is touch.

* In our lips, there is a dense concentration of a specific type of nerves which may explain why kissing is a sensual experience.

* Our skin plays a role in attraction, not through touch but through chemistry. (This is prior to touching each other.) Our skin is full of pores which releases chemicals called phernomones. It is especially concentrated in the armpits and groins. Research has documented phernomones in sexual selection amongst animals, leading to research on phernomones in sexual selection amongst humans.
