go on then ,ill stick my neck out,a lot of native tribes living in jungles do not have beards,(waiting to be proved wrong)i think there was a recent tribe who lived in the amazon had no contact with outside (civalisation?)contact but did not have beards maybe the disposable razor is not a new invention.but to be honest i give in.why didnt tarzan have a beard? awaiting punchline .but then again, have you ever seen a native red indian with a beard?
