That is also my personal belief. I have cardiac issues, and simply getting out and being physically active works. My excessive physical activity is fully approved by my med people.
The worst thing a person can do is retire with a TV remote control in one hand and a six pack of beer in the other. Sadly, my brother did that. His recliner was his best friend while he became morbidly obese and paid the highest price for it at an early age.
Many people think with heart related issues one should just sit back and relax and not do anything physically demanding. One such person was my American Legion rep to the VA for claims. I walked a half mile to her office once and she chewed me out for that.
It is literally the answer. I preach the same thing to everyone.
-Brace your knees before they hurt.
-Move around. Wander. Go places. Do the Walmart 500. Just wander aimlessly while you shop at a store.
-Eat responsibly. You know the right thing to do so do it. Carbs are the problem.
-Dress nicely when you go out. The thrift stores are full of dress clothes. Wear a nice $5 sportscoat. Wear a coat and tie for no reason. When you look good, you feel good. You don’t want to be staring at the ceiling of a nursing home lamenting “I should have used the good china”.
-Exercise your brain. Read. Listen to podcasts while traveling. Write in a journal. Plan your day, every day, every week, every month. Document what you do. Turn off the TV, turn on music.
