Well, I do agree with you. Walking daily is really helpful. I have seen its importance.

One thing that I would like to share with you all that walking daily in the morning is unlike any other medicine, where you need to wait for sometime to see its effect. But with morning walk, you will feel yourself charged and energized instantly... Surprised... try it..

And as TheMaxx said, avoid smoking / drinking and eat healthy food.

Thanks TheMaxx for sharing your view with all of us.
