Discovering tennis and becoming a die-hard player in my 40’s, I naturally wish I’d started earlier, especially as I face opponents who did. Despite ample coaching and court time, I can’t seem to match those who learned and drilled the fundamentals of the sport in their youth. Even these guys, however, talk with some regret about getting older and losing the athleticism they once had. It’s reassuring to know I’m not the only one sometimes wishing I were younger.
