Is basketball a hobby? I have been playing less and less the past couple of years. With my knee and back problems becoming more frequent now, I decided it was time to quit. The only time I’ll probably play is with my highschool friends who are at the same level of fitness and physicality, and we meet only every few years or so. I can’t show up at the rec center to play with randos anymore, because you never know how hard people play, and I can’t keep up anymore.
