Didn't he take 3 walks a week?
Following a triple-bypass in 1983 at age 40, I took up running. I ran/jogged almost every day for 16 years. In 1999, my joints hurt so much, I quit jogging and started walking five-six miles a day. Now, at age 65, I SHOULD weigh about 150 on a 5’9” frame but I have to struggle to keep it under 200. Blood pressure, with medication, is about 125/80; cholestorol/LDL/triglycerides are all OK, also with medication. I haven’t smoked in 32 years.
