What "activities" that are widely accepted as sports do you not count as sports? A big one for me is golf. You can be 100 pounds overweight and still be great at it. You drive carts around instead of walking so you don't even have to be in good walking shape. I think it's absolutely not a sport because it doesn't require any sort of physical fitness besides practicing. Learning to point a mouse on the computer requires practice too and that's also not a sport. Golf is a social activity at best. I also don't consider things like pool or poker to be sports. Yet they both show up on ESPN from time to time.
