Older Jellies (in the 40+ age range, please) have you fairly recently revisited old interests? (please see details)

Have you picked up an old hobby that you focused on long ago, revisited the memories of a former career, metaphorically unpacked an old, important box?
For example, in my 20s, my life was wooden boats. I was a broker, and I had a business doing repair and cosmetic work on them, then I kind of adopted one that limped into our boatyard and refurbished it.
I went to the wooden boat shows, I subscribed to Wooden Boat magazine, I coordinated availability stats all over the country for interested parties.
Then my life went in a different direction, and all that drifted off.

Recently I found a business card from those days and I am getting a lot of joy picking up my interest again. I’ll never immerse like that again, but I enjoy reading about them, seeing them in marinas, and talking to people about them.

What about you?
