I'm not deluded enough to think it helps performance in any way, but maybe helps after a fall? Pulling plasters/bandages off scabs?
I did shave my legs once (last summer), and can't comment on healing powers as I didn't fall of whilst my legs were hairless.
I can comment that it looks really quite weird for a hairy man (scalp excluded of course) to be hairy on top half, and not on bottom half. </TooMuchInformation>
I wouldn't do it again.
Well, who knows, maybe?
