Well, thank God you added that disclaimer "including but not limited to" otherwise I would think you are a man with no ambitions....Life is what you make of it, and you only live once. If I work hard to maintain good mental health and decent physical health as my age increases, I can think of a plethora of activities I would find extremely rewarding including but not limited to:
Helping raise my grandkids (if either of my kids decide to have kids).
Traveling the world with my future wife.
Variety of online games.
Trying to become a chess grandmaster.
Learning pickleball if for some reason tennis is no longer playable for me.
Chasing fishing world records.
Trying to win a WSOP bracelet in Texas Holdem.
