At age 33, I joined a senior-citizen badminton league. It wasn’t restricted to seniors, exactly–the rec center called it “beginner” badminton–but I was the only player under 75. The guy that taught me to serve was literally 94.
And those old dudes kicked my ass. I was an actual beginner–never held a racket before–whereas most of these guys were practicing for the senior olympics.
Sometimes, it seemed a little pathetic, playing (and losing!) matches against people more than double my age. But they were really nice, and willing to coach a new player. I showed up 3 mornings a week all winter.
By the spring, I had improved enough that the rec center bumped me up to the intermediate / advanced group, which is filled with a bunch of younger Indian players. I still love the game, still play a couple days every week–but there’s absolutely no way I could have gotten started if the old folks hadn’t been willing to show me a thing or two.
