A friend of mine (same age, 43) is always complaining about being overweight and needing to start exercising. Every time I go to his house, I wind up on the trampoline with his 9 year old son and 9 year old niece and whatever friends they have over. I usually bear crawl and swipe their legs out from under them while they bounce around me (their favorite game).

I'll go inside and collapse on his living room floor. I'll look at him and say "You're always saying you need to exercise and be more active. Get out there and play with those kids." He just looks at me like I'm crazy and says "No!"

Like I said, maybe I'm just a big kid.
