I grew a beard some 30 years ago because I was lazy and because my curly hair kept causing painful ingrown hairs on the face.

A beard is great because when we go on lengthy trips I just take one "disposable" blade for the weekly trim around the edges. Sure helps keep backpack weight down.

I highly recommend growing beards - but gee if most men do that how are people going to tell the difference between terrorists and non-terrorists?

They had a re-useable razor on a TV antique show-and-tell segment. It had a kind of mini belt sanding action, brand name Rolls I think. That has to be due for a comeback.
