I never really wear my helmet when I'm out riding, unless I try something new/big, that i'm not sure that i'll make. Although I don't really go big anymore, just ponce about doing small, techy stuff. I know I can fall off and hit my head etc, but it's my choice. I'm confident that I won't fall off, and if I do, helmet or not, I rarely hit my head. Call me stupid, I couldn't really care... Anyway, glad to hear that he's recovered so well! Hope he gets back to his usual self soon...
