Anyone who actually lets football make them unhappy is being stupid IMO. Sure you are bummed out......for about 12 hours etc. After that if your life is right and you have really important things going on that you can control you realize that sports is no different then a movie. Broncos football can make me excited, happy and be a ton of fun.
I was more upset when I lose my fantasy football and all the money that would have meant 3 weeks ago lol. I used to get super upset over the Broncos but grew up and realized its just a sport and being more upset then the players get is not very logical.
