None, as far as I know.
However, I shouldn't pet my cat (Simba) a lot, but I still do it because I don't want her to die unnaturally like my first cat, Raichu, died. He got hit by a car on 23 September 2003. Anyway...
I greatly enjoy going onto the forums, even if I shouldn't (without my parents' permission but they'll never give it to me). I've learnt a lot since I joined a forum for the first time.
Does that count?
