I had lots of marginal health issues in mid-50’s. Lucky me decides to resign from a well paying secure job and begin exercising 5 times a week. My choice was golf because it is for me least boring exercise. That fixed every one of my health issues! I quit golf at age 75, but continued mild daily exercise, mostly walking. I am convinced that is the main reason I am still alive and in decent health.
You’ve made good decisions and adjusted things as you get older. Good job!
