Good, but you forgot to add great sex with wife or life partner. If one is no longer attracted to spouse I suggest an upgrade just like the wealthy do. Remember, what is Holland & Holland, Purdey,.... when compared to spouse half ones age or younger, how about nothing.
I could not find your attempt at humor in suggesting breaking one's wedding vows for an "upgrade" more tasteless. Selfish amorality, if only in jest, is a poor substitute for character and commitment.
While the media may make it appear everyone walks away from commitment. My circle of friends all seem to have original wife and appear happy despite your posited lack of upgrade.
Returning to the subject of the post, fitness, it is painfully simple, be active, burn the calories/Carbs you take in, and lastly have a routine. None of this is as easy to do as say. Like marriage it requires commitment.
