Agree 100%. I am living example of someone who cured his pre-diabetic condition, chest pains after a good restaurant meal, bone on bone knee pain, hip joint pain, irregular heart beats, panic attacks in closed malls, elevated blood pressure and fainting spells at work at age 55.
All I did was quit job at age 57, and walk 30 miles every week playing golf. Every one of my above listed problems were gone by age 65. No pain anywhere in this 80 year old body. I just had blood work done and doctor said everything looks good. I am looking to join a ballet class.
I expect to feel just as athletic at age 100 if I continue my half hour tread mill every day.
