One of the reasons that I don't follow sports (except the occasional golf tournament) is because I carry a jinx gene. Any team or specific person I really like and want to see win, will not win if I am watching (I take that back, twice, first time in 1969 when the Mets won the World Series and again when Jack won the 1986 Masters). If I watch any other and I pick a team, they will lose, guaranteed! I have developed a system where I will back whatever team I do not like just to make them lose. It isn't a fool proof system, but it keeps my blood pressure at a safe level.
I'm thinking that I might be able to turn this into some income generating setup. I could charge certain sporting teams or individuals to become a fan of their opponents. A pay before play type of system.
