What hobbies did you suddenly develop in your 30’s?

Does anyone have hobbies in their 30s that their younger self would be completely shocked to see?

Hobbies I expected: Crocheting, gardening/houseplants

What I didn’t expect: Watching sports routinely- I regularly make plans to watch NFL and WNBA games. This has given me so much joy when it comes to spending my alone time and I get slightly nostalgic thinking of my childhood players and how we are seeing the new wave of generational talent. Now I go to games! Been to 2 WNBA games with #3 this week!

Any other hobbies that developed in your thirties that completely surprised you?
