Retired recently. Want to keep CDL valid and usable.

I retired a couple months ago I originally wanted to wait until January of 2025, but the closer I got, the more I couldn't stand it and gave my 2 weeks. Hehe the countdown was killing me!
A couple weeks ago, I had my Med Card renewed for $75 bucks by a Chiropractor who was licensed to give CDL physicals. I never want to go back to work, certainly not full time, but I want to keep my options open. Now just keeping my Med Card is only part of it. Most companies want some experience in the last three years. So I need to figure out how to be able to show some experience, periodically to stay a viable employee.
Has anyone else wanted to do this? What would be the minimum experience per every 3 years would I need to stay viable? Where could I work the absolute minimum to pull this off?
My work history is exemplary- last ten years, no moving violations, no DOT accidents (did break a mirror in an icy parking lot), never put it in a ditch. I did have a 10mph speeding ticket but that was over 20 years ago. Currently have HazMat/tanker, Doubles/triples endorsements. I'm 66
Opinions?

 

Omaha- I'm in Omaha

 

over 20. BTW I was food service-local and then Line haul the last 10. I'm only doing local stuff, if any.
I don't need to work (unless my planning was WAY off heheh) I just can't wrap my head around letting go of my CDL. Like it's my security blanket, or a part of me. Maybe that will change after a while, but now that I'm retired it just seems important to hang on to it. May be irrational.
