I am a fan juggling, but I also enjoy watching people who have taken their physical skill to the highest level. I am not a fan of football, but I am amazed when I see someone like Emmitt Smith zigging and zagging through a pack of defenders. Gymnasts, divers, tennis players, skiers, skateboarders can all be exciting to watch. Tight-rope walkers, wrestlers, pole climbers, balancers, sword-swallowers, fire eaters, trapeze artists, and stuntmen are terrific. Slam dunks, pratfalls, free falls, backflips, and pirouettes are beautiful. I just recently discovered Dancing with the Stars and So You Think You Can Dance and I find it fascinating. Another great source of video of human movement are Nike and Gatorade commercials.
