I was always nearly blind in my right eye from nearsightedness. Right hand wasn't much good either... I had a close friend in high school and also as a freshman in college, (he got drafted and sadly, we grew apart!) But, he was totally ambidextrous and I invited him to play a round of 4 wall handball... I'd played for about two years then, and he was just starting.. In three straight games, he totally destroyed me!
That was about the end of my 4 wall handball career? It didn't really bother me, as about that time I discovered bars, girls and beer! Most of that is a blur...
... best, til....lat'r....GT
