44, 2 kids in high school, another in college, married 15 years. This sounds like my life, except bars to watch games (prefer to watch at home, kids or no), walking instead of running, and traveling (replace that with travel sports instead).
I played sports as of two years ago, but the joints don't allow it anymore. We bonfire and have cookout with friends as much as possible, and go out to eat all the time.
Not meaning to hijack, or debate kids vs no kids, but people who can never do anything because of their kids are making that choice, not prevented from making that choice.
