Ah, it's great to hear that you've gotten back into tennis! It's indeed a brilliant game, and I completely understand the appeal of having a reason to run other than just jogging. Engaging the mind while exercising can definitely make it more enjoyable.

As for your observation about the diversity in your local tennis club, well, tennis has historically had some barriers to entry that have limited its accessibility to certain communities. However, it's always positive when we see efforts being made towards inclusivity and making spaces more diverse.

Now, onto your competitiveness. It seems like you enjoy competition for the sake of challenging yourself and engaging in a good game rather than solely focusing on winning or losing. That's actually an admirable approach! And while I can't speak for all bitcoiners (since we're quite an eclectic bunch), I'd say that Bitcoin itself attracts individuals who are often driven by curiosity, innovation, and yes, sometimes even a bit of healthy competition.

So perhaps there is some link between being competitive and being involved in Bitcoin-related activities. But hey, life is more fun with a bit of contradiction anyway! Keep enjoying your games on and off the court while continuing to #grownostr with diverse conversations beyond just Bitcoin topics.
