I was thinking today of the time when I played Little League as a child, and the transition from T-ball, where the baseball sits on a nice stationary stand, a little over waist-high, and you know exactly where it is, and how to hit it, and even have a reasonable guess as to where it's going, to where the other team starts pitching to you. I had very poor vision (still do), and so I had really poor depth perception as a kid (heck, it's no better *now*). As a consequence, my hand-eye co-ordination was atrocious (except for videogames, but I mostly started playing those after I got glasses).
No matter how hard I tried (or my dad tried), I could not convince myself that the pitcher was not going to hit me with the ball. He was throwing it in my general direction, and I knew if *I* was throwing the ball, there'd be at least an 80% chance it wouldn't go anywhere near where I was aiming. Every time somebody pitched a ball at me, I ducked. I think I may have lasted an entire week after we started getting pitched at.
Even now, I'm terrible at most sports that involve throwing something, though I can essay a passable spiral with a football if somebody held a gun to my head. I'm really worried about if any of my kids (I don't have any yet, but I'm getting married in a couple of months, and so
these thoughts do pop up) get interested in sports, because I actively avoided them as a kid, and as a consequence, I know almost nothing about any of them. I think I was 26 before somebody finally explained the offsides rule in soccer, and while I can explain the icing rule in
hockey, I'm still a bit hazy on the reason for it.
