I have a Warhammer 40k Blood Angel-style tattoo. I would prefer not to have it, not just as it seems a little ludicrous, but because now I see it as self-mutilation. I nearly decided on lettering reading 'Only the insane have strength enough to prosper; Only those that prosper cant truly judge what is sane', which was on a Games Workshop t-shirt I wore until it fell apart. The transitory nature of haircuts, or clothing are more appropriate for self expression in my opinion.
