Medicine, John Callaway is part of a special exercise program called PREVENT. A battery-operated

heart pump called an LVAD keeps his heart beating; he walks, works out, meditates and

learns about health and nutrition in PREVENT, a medically-supervised exercise program for

people with long-term health issues. Sometimes I forget that I even have it on. A small control

box runs John's LVAD, or Left Ventricular Assist Device. Two battery packs at the belt

on his waist ensure he always has power and a backup. A small tube runs into John's belly

with wires feeding electricity to the pump that keeps his heart beating until he receives

a heart transplant. One of my brothers, they call me the Iron Man or Bionic Man cause I

have my equipment. The LVAD has helped John come into the PREVENT program and exercise

and like a lot of other LVAD patients we see, help improve his strength and endurance and

ultimately help him live a better life.
