Hi Dr Bobby. Love your show. Thank you for the informative sessions on health; I appreciate your science-based approach and I first heard you on The Retirement answer Man. I would like to hear more - for his show or yours -specifics on different exercise methods as we age. One has to balance joint wear and tear with opportunity for muscle increase, and general health, no? ( I started rucking recently with 5 lbs strapped to my waist- I was a runner for many years, so I dont want to wear my joints out). I also bicycle 30 miles/week, do yoga and a little weight lifting . How do joints go bad/ need to be replaced? From underuse, overuse, genetics? Overweight? Thank you!
