I would have to say Football and Baseball. Love to go to the games and watch them on TV. How do they affect my life? Pure enjoyment and an excuse to eat Pizza. Love both of those games and my favorite teams. Football ties up my Sundays quite often. They are my favorite as I used to play Baseball and Football is just great to watch. Other Sports bore me.
I love football!! Why? Football food and beer! I also enjoy baseball....I'm a reds fan, but a certain person...ahem...thinks I need to root for the A's! THAT should be interesting! Basketball playoffs I can watch, but don't necessarily care for....otherwise, no thanks!
My favorite sport is soccer... You run a lot, the Mexican food they sell at games, and I just love that sport!
