What kinda of diet and exercise can a 48 yr old 450 pound man suffering from heart failure with a defibrillator in his chest do without killing myself?

Falls are the #1 Killer of people over 65. Set a timer for 60 seconds and take a minute to balance barefoot - be sure to do both sides 😉 don’t go crazy - hold on to something if need be! A little practice here and there adds up to a lot!
