Best invention ever: quality razor blades!
I can't imagine having to shave with a sharp rock or a a clam shell..Ouch, that would hurt...
I can grow a half decent beard, but I hate 'em...
I haven't had one in more than 35 years...but I do have trimmed mustache..
Most chicks don't dig beards..
Oh, and if you can't grow grow one,,shave that fuzzy shit off..
Isn't Mother Nature grand !
