(F 30s) how to best prepare for my sixties?

r/

I am in my mid thirties. Women have a higher chance of dementia and osteoarthritis in old age. What should i do now so that my future self thanks me?

I speak,read and write in 3 languages. I picked up a fourth for some good new neural pathways.

I started learning to swing dance 4 months ago and don’t plan on quitting.

I try to eat different nuts daily and have my 5 or more veggies. I get enough protein.

I exercise for 150 minutes a week. I know it is the minimum but i have a fulltime job and a child.

How else can i do better?
