I continue to be amazed by our bodies' ability for self-repair. ... Our bodies want to be healthy, if we would just let them. That's what these new research articles are showing: Even after years of beating yourself up with a horrible diet, your body can reverse the damage, open back up the arteries-even reverse the progression of some cancers. Amazing! So it's never too late to start exercising, never too late to stop smoking and never too late to start eating healthier.
