This is a very interesting, if not painful, topic for me. Glad to see this thread. I have the opposite problem. As a lefty bowling non-stop since age 3, it appears I have peripheral neuropathy and can't lift my right foot. Something happened on a business trip, but who knows what. Neurologist hasn't found it yet, but I'm down for at least 6 months, maybe permanent. It's amazing what small muscles must do to balance a bowling approach. I tried walking to the line and as soon as my left hand went back and I tried to balance forward, I fell over.
Glad to see some of you think switching hands is a game, but I can't agree. I can't quit bowling, it's been a part of my life for too long. But why the @#$%^ would I want to compete if I can't break 120-140? I just don't see it.
I'm out for the winter, and hope to heck I can make El Paso since will be my 25th year. There's a big difference between a positive attitude and reality, but I have to tell you. Some of you willing to fight thru honestly with an injury are making me rethink trying right handed. Not sure I can walk to the line, but I might just have to go find out.
