As I was running this morning, it kind of struck me that a lot of health issues have to do with blood flow.  Many type 2 diabetics have problems with blood flow to their lower extremities, and often a main contributing factor to type 2 diabetes is weight.  High blood pressure, arteriosclerosis, heart disease, etc. are all related to blood flow.  If you keep moving, keep getting your heart rate up daily (as long as your physician has cleared you), you will keep that blood pumping, as well as burning off the calories, keeping your weight within normal limits, keeping your muscles strong, your lungs functioning.  Daily exercise is a powerful medicine.  Your body needs that blood flow to keep your systems working at optimum levels.  Don't settle for functioning at minimal levels.  Get your body to do what it was designed to do.  MOVE IT!
