Exercise also helps. Been exercising religiously since age of 15 (50 years) and when home-rehab folks came in after my hip replacement (wore it out by running far enough to go around the world and then some) they told me that I wasn’t the typical 65 year old that needed their help doing the right exercises - they said I was “an apparent 50” in good enough shape to be as vital as the average 40 year old.
Nobody believes me, but TM is the best thing for your psycho-physiology. People think I’m in my 40’s. Ha!:)
All the best to you and yours.
