I found this video to be particularly interesting. I'd heard that watching a sport did make you better at that sport because when you play, you'd visualize it. I was wondering if that idea had anything to do with the one presented in this very video. So, therefore, I can become a better football player, swimmer, tennis player, etc., simply by imagining or watching it? Apparently, you can even increase muscle strength. Just thought you guys'd find this to be pretty interesting.
