Dead of a heart attack at 51...

As quoted above... you can’t outrun your genetics.

As my father in law used to say....you ever see a happy jogger?

How many WWF wrestlers from the 80’s are gone now? They all died in their 40’s and 50’s

I would like to see their “supplement” regimen.

I don’t know about “happy joggers” but I sure know many happy runners. I really enjoy running. You should try it.

Steroids destroyed their hearts.

I do....6 days a week for an hr...hate every minute of it

That is heavy duty running, unless you're running very slow. If you're hating it, you should change it up, alternate with biking and hiking, anything else. Life is too short to be miserable. I do a lot of running and my spouse is an ultra fitness type, but couldn't imagine doing something we hated.

Ditto!!! Be happy...

Exercise is important and it helps establish healthy sleep patterns.
I wont downplay exercise however I think dietary habits are more important. The men that I know who have survived this career are all at a reasonable weight and eat well.
