Doctors and other says walking 5 days in a week is enough. I am a diatebitc walking 2 hours daily. Why they prefer 5days walking in a week?

Doctors' advice is right. Recently I came to know that excessive exercise causes more free radicals in the body which our system cannot handle. Do you know sportsmen, or fitness freaks who exercise excessively as a fad for very long period even beyond their young age, in many cases, die of cardiac problems or get affected with cancer etc. It is all an established fact.
