Why are tennis, golf, etc considered lifetime sports? I used to think it was because they were more easygoing sports that you could play even when you got old, whereas you couldn’t do that with basketball, football, etc. Now I think that tennis/golf/etc are lifetime sports because you can play them with fewer people. You can play golf by yourself, and tennis with only one other person. That’s sort of a depressing thought. I know for myself, I played basketball/football/soccer/etc more in the past when I had more friends around and more time to organize games. These days it’s hard to get a game so I play more solitary sports like ping pong.
