In regard to "regression"; presently, I'm attempting to stay in a steady state of "mellowness"; that is the same frame of mind I have always preferred; maybe I'm regressing back to that.
In regard to music, I just ordered a CD, "The Diverse Yuseff Lateef" because my vinyl copy was too noisy. I thought about replacing Grant Green "Idle Moments" LP, but since they're asking "50. bucks, my old LP really doesn't sound that bad; "equanimity" sounds like a good word to express my attempted state of mind. (it's fun to use a word when You're not quite sure what it means, lets look it up)
am-webster.com/dictionary/equanimity
Both "equanimity" and "equal" are derived from "aequus," a Latin adjective meaning "level" or "equal." "Equanimity" comes from the combination of "aequus" and "animus" ("soul" or "mind") in the Latin phrase aequo animo, which means "with even mind."

Sounds close enough. My old music is still sounding very good in rotation with anything new that I acquire; I don't know if that's regression or not; I'll let you make the call.
Yes, I am so inclined and will place that CD on order.
Enjoy the music.
