Interesting post, OP. Kinda sucks being a guy, 'cause we are often limited with what we can wear on our arms; you won't see me donning pink bracelets, put it that way. :P Problem is, they draw a lot of attention. I would probably make my arm more obvious, with one, than if I didn't wear one. I'm quite used to wearing shirts, coats, jumpers, fleeces, and what-have-you, so I'm not too fussed. It can be pretty brave to be going out knowing your scars are visible; took me a while to get up the courage to do that, but mostly of the time I do definitely cover up.
