If you’re interested in a deeper dive, this is basically a summary of Peter Attia’s Outlive
https://peterattiamd.com/outlive/
It’s a good book, I’m currently reading it now. The premise is: if you want your later years to be healthier (as thoroughly defined in the book, but covering physical and emotional wellness), you need to start early with a long term plan
So far so good, I’m enjoying it
