Just look at all the worlds heartthrobs, in the eyes of the ladies that is.
George Clooney, is always near the top of the list, and he is alway's cleanly shaved.
Back to a different era, Carey Grant, Clarke Gable, Ray Milland, James Stewart, the list goes on, all beautifully clean shaven, real magnets to the girls.
Just look at what a beard did to Charlton Hestons amazing looks, when he played the role of Moses in "The Ten Commandments" Blimey he looked old, it aged him terribly.
Possibly a beard, like tattoos, is a more recent addition, or fad, some women find it attractive, but i bet most prefer a handsome gentleman with a splash of pong behind his ears.
Somehow i how cannot imagine Fred Astaire or Gene Kelley strutting their stuff with a full set.
