I have no opinion about running on whether it’s good or bad for you, but here’s one observation of people who run; in almost any conversation they use the words “me” and “I” more than others. There are many examples, even on this thread. It’s all about “me”.
My running is about me. I’m not doing it for anyone else. It’s not a charity event that I do, or to take care of others. I’m also not asking for anyone else’s help or permission.
I would hope that you and everyone else have things that you do for yourself as well.
We are all responsible for taking care of our self on one level.
Not sure why this is would be unusual. Some people fish; some people watch NASCAR, some people garden. We all have our things.
