@OmSigDAVID,
Ah boom - my original point -
Some people like reading/some people don't
Some people like sports/some don't
I think it could be a variety of reasons why you like or do not like something (of which part could be your past experience either positive or negative).
Seems David you don't tend toward being competitive (or perhaps physical). Curious - are you competitive in other ways - ie like to beat others academically or at a board game or trivia?
