Hair Today...Gone Tomorrow!

A male face has between 10,000 and 30,000 whiskers, with the average number somewhere around 15,000 to 16,000.

A single facial hair grows about 15/1000ths of an inch each day, or almost 6 inches a year.

Shaving removes about 65 mg of whiskers per male (on average).

Question #1: If a man let his facial hair grow from age 18 until age 80, how long would you expect his beard to be (in feet)?

Question #2: Given every man in the United States' population, if all of them shaved and their beard hairs were gathered into one pile for one day, how heavy would that pile be? What about over an entire year?
