Thanks for posting the article.
I'd say this: push yourself. I'd rather play up a level or two and get bageled than play the same kinds of matches against the same five or six guys from league play.
My club has a pro who is ambidextrous and I've learned more with him playing lefty (he's a 4.5 lefthanded) than maybe anything else. Seeing the opposite hand taught me how to anticipate chips and drops really well, even if it meant buying him a few beers as penance for taking the bagel.
Use it as motivation. My father-in-law is 83 and is a national super-senior triathlete champion. You better believe that motivates me at the gym and in the pool.
