but say you had your EKG, and the doctor said, your not allowed to excercise any more?
I think you’ve raised an important point. I would guess that most doctors would err on the side of caution in giving a prognosis, and although some lives may be directly saved, many more lives might be shorted by people being warned off exercise. Plus if it became mandatory, or heavily advertised it would lead to people percieving exercise as dangerous, which is the last thing we need.
