Why should someone stop doing what they love and what makes them happy? Life isn't all about just health and safety unless you want to live a boring passion-free life. I never get those people who spend a ton of dough risking their lives and putting themselves through hell just to climb a mountain. A person I know who is into climbing and hiking said he does it because he loves it. It makes him feel alive. I get that. I realize it's the same as when people tell me I should give up Jiu-Jitsu because I'm so old and injury prone. But that's what I like to do. The price paid is worth it to me. Just like those mountain climbers and has been bodybuilders.
Same here.
Last week a good friend of mine and I were talking about extra curricular activities and I brought up how through my whole life that the people who questioned why I like working out were the same who had no problems themselves spending up to 3-5 times more hours a week doing what they enjoy like for example golf, watching/playing sports, playing/listening to music, art, knitting, drinking and posting on getbig etc.
In the end it's really none of our business what people like to do, especially if they are not directly affecting anyone else in a negative way
