"I have a different constitution. I have a different brain; I have a different heart; I got tiger blood, man."- Charlie Sheen
In this quote, it could be quite possible that Sheen is implying he has actual brain damage. To be honest, anyone who has used and abused that many substances is not going to walk away mentally stable. Charlie does not have "tiger blood". He has human blood that's probably floating around with a mess of STD's.
However, behind his antics could lie a real cry for help. Perhaps Charlie does seek attention--but from that of a therapist or doctor. In this country, we celebrate genius and often, hopefully, the intellectually unique. However, in Charlie's case, he's so convinced his mental instability is in fact genius that he calls those disillusioned by him "trolls".
It did make me sad, however, watching "The Roast of Charlie Sheen" on Comedy Central last night. He was a good actor with a lot of potential. Well...he still IS a good actor, unless his lifestyle fatally derails him.
