I've had reactive hypoglycemia for years, and exercise if one of the things that helps me with that. As for motivation, I live in condo building. My upstairs neighbor is about my age, and she is suffering the ill effects of not taking care of her health for years. Between hearing the floors creak as she shuffles around in her unit and seeing her slowly walk to the elevator to go up 1 flight of stairs I'm motivated to take better care of myself to avoid ending up like her.
