I don't really play any sports, especially these days. I had a hard time fitting in and working well in social situations so I had no interest in even attempting team sports as a kid. Later on - but back when I still had some friends left - I did enjoy the occasional 5-a-side football, but I was never a sporty kid.
For watching sports, I find I can get into almost anything if I give it a chance. My favourite is the Olympics, and getting hyperinvested into niche sports for a month every 4 years. Otherwise I am a big F1 (and general Motorsports) fan. I used to be really into watching football (soccer) too, but that has sort of cooled into a more casual interest over the last couple of years. I still watch games frequently, but it's not the same sort of obsession.
