The desire for physical change rarely comes from wanting better health. It comes from the fear of losing it or even fear of how you're viewed by others. Heart attack, stroke, and injuries that impair daily function and quality of life often serve as a wake up call. Not looking good for a social setting such as a wedding or reunion scares people into taking action. Action is often taken too late and all who can relate wish they had taken charge sooner. You always think you have more time until you don't.
