I don't consider myself an "average" fan by any means. But my days of living and dying with each win/loss are over. I live and die with my teams' wins and losses but I'm usually able to get over it within 5 minutes now. I was much worse 2 years ago as most here would attest to. My mood can be altered by wins/losses, but like you it usually lasts like 5 minutes or so. When I was like 20, people couldnt be around me when my teams lost. Pretty sad thinking about it in retrospect. For me it's all happened since the 08 playoff collapse. Also being around the game much more often has helped, but the collapse is really what did it. I just decided it wasn't worth it to be that involved in the win/loss outcome anymore.
