Pulling the trigger

[Outlaw Josey Wales]

Retiring, allows for a freedom I wish I had when younger. Things are good. Except for the health. I noticed you mentioned that as factor. For that reason, as has been mentioned here, savor the time doing what you like to do.
I've been retired for four years. I think I've enjoyed my time (don't remember it all).  I joined a Gym but Having difficulty in walking I don't' think I'll keep up the membership. watched a lot of television. That becomes boring as hell. As you mentioned, wanting to take up something, eventually.

So to break the boredom, I took up something I could do. Ubering, Lyft (not Uber eats too physically demanding so just take on riders), can actually be a good activity for a retired person with physical limitations. Your the boss, work as much or as little as you want. I like it. I do have to watch myself and limit my driving (old habit of working many hours wants to creep back in) however, as a retired person it works great.
Best wishes for a fun filled retirement.

I've been at it since 2007 with degenerative arthritis and the added stroke since 2016.  Haven't left the house without my wife since then.  So, I game, watch youtube videos,dogs and cats are the best, and picked up Out of the Park Baseball.  There are just too many ways to get unbored.
