Obviously there's plenty of ways to exercise without playing sports ball or any team based activities OP, don't make me list them all 😅

I wouldn't advise sports for health anyways, that's usually how everyone involved in sports I know acquires significant injuries and permanent body damage!

Do whatever. I walk around my local green belt after work each day or night since I work rotating shifts. I get home and do a minimal equipment workout in my basement gym in the style of George Hackenschmidt, a classical (pre-steroids and targeted workouts requiring gobs of equipment) professional strong man, ride my bicycle around the city bike trails in summer months, use a rowing machine I bought used in the winter while watching Futurama or whatever I don't have to pay much attention. Took up dancing and kick boxing. I don't like those last two very much but it's more about preventing my social skills from atrophying tbh, gotta exercise that too! Nothing I listed is what I'm saying you should do, it's just examples. Find stuff you can do with your current body condition without risking injury. Doing a regular walk daily is a great start alone.

Well, when it's not 40+ outside with 100 humidity at least. I've visited Hungary in a heat wave before, absolute fucking misery.
