I played lacrosse from grade school through the first half of high school, and then again in college for a couple years. I switched from Attack to Goalie right around the time I realized that I really don't like getting hit by big dudes wielding metal sticks.
By the time I realized that I also don't like being hit by a hard rubber ball travelling at nearly 100 mph, it was too late: I'd made the team. I think the two years off in high school helped me get ready for a couple more seasons in college, in much the way that a woman will sometimes give birth to a second, third, etc., child. The passage of time dims the pain and highlights the pleasantness.
All this is a long way of introducing an observation: I would probably be really bad at Ultimate Tak Ball.
