Yes addicting is probably the right word. My wife thinks I’m crazy and she works out. So do a few of my friends It’s not the fact I try go to the gym 5-6 times a week. It’s more the intensity . It’s hard for me to explain. I don’t enjoy the thought of going to the gym because I know 90 % of the time it’s going to be painful. But if I don’t go I know I will feel like shit so I go and then I feel great when it’s done. I mean like on top of the world. Definitely endorphins kicking in.

I love your second paragraph. That’s it exactly. What you do in your 40s 50s and 60s will set you up for a healthy and active 70s and 80s I am no expert but I think if you are an overweight couch potato going into your 70s it’s very hard to turn things around.
