I have a few friends that work with autisitics.
One of the things they are always saying is that "everyone is one the spectrum."
Like any guage of behaviour, like autism, we all exhibit some degree of OCD, just not much point labelling yourself unless it is ruining your life and you need help.
Although like LS says, if typing about it makes him happier then why not, and if Becks helps people feel better then why not.
Just gotta watchout out for fraudulant incapacability claimants using it to get signed of i guess.
IMO
