To be a street cred you need not risk with your life anymore. Just use a little brain and see how amazingly the things work. The scratch on that guy’s bare chest made me feel he had a recent skirmish with a werewolf or something like that! There are many such available — wounds, stitches, scars to name a few. Displaying them is going to allow you grab attention of the people (I mean babes) you always wanted to. Then you should be smart enough to make fairy tales of your valour. I recently had one of these fake scars displayed on my arm — and trust me, the results were amazing! So what are you waiting for? Heroes are heroes, real or fake!
