Think on these.....

 This has proven to be very true in my case.  Good, natural food can have a medicinal effect on a person.  On the other hand, over processed icky food ALWAYS makes me feel like I am being slowly poisoned.  I think that the more I eat good food, the more sensitive my body is to icky food.

I have always just ran, and ran, and ran some more.  And, while I do like running, I have always done it, and I have always been at the high end of my healthy weight.  I am beginning to LOVE weight training, and I am already seeing results in my strength and my body composition.....
