I have come to the conclusion that degenerative events such as calcification deposits in arteries can be minimized by making the heart work harder with exercise.
In many ways the car engine is similar to heart function. If you drive at slow speeds a lot in heavy traffic, carbon sludge builds up. Driving at high speed on highway occasionally cleans up carbon deposits. Exercise may be doing same thing for the heart.
I exercise daily for 25 minutes and knock on wood, have zero issues with heart at age 82. As a side benefit have not had a cold, cough, flu in 15+ years.
What type of exercise do you do?
