Some "hair" Did you knows...because I'm studying:
Averaging out the human body, each square inch of human skin consists of 19 million cells, 60 hairs, 90 oil glands, 19 feet of blood vessels, 625 sweat glands, 19,000 sensory cells - and is normally inhabited by anywhere from 10,000 to a million bacteria.
There are between 100,000 and 150,000 hairs on the average person's head, and nearly 400,000 on your complete body.
Babies have about 1,100 hairs per square inch, but by age 50, this drops to around 250 per square inch. (Bad news for you Phil! )
Each hair follicle will grow an average of 20 new hairs in a lifetime, at an average rate of a centimeter to a half inch per month - so if you lived to be 100 years old and had just one hair that never fell out, it would be over 12 meters (12 meters = about 40 feet) long.
Although humans may appear "naked" by the standards of other primates, we have more hair follicles per square inch than most other mammals.

How in the heck do I get dragged into these things?
MaDamn Moderator, FYI: Although I'm what's considered "smooth" and have very little body hair and chest hair, I do have a full head of lush hair. I have some friends that started balding in their early 20's. It's a gene thing.
I personally just counted all the hairs on my head and I have an average of 1076 hairs/sq-in. NO balding, no thinning, and NO shit!
Until I was about 35, I only had "peach fuzz" and I didn't even have to shave facial hair.
Now, at 39, I have to shave daily else my beard would look like Will's chest. >>> Phil
