Encouraging healthy lifestyles is important. Billions are spent on diseases and illnesses that could be prevented.
I propose that the government offers a reward, in the form of a tax incentive for people that maintain a healthy lifestyle or make life changing decisions to improve their own quality of life.
For example; a person with high cholesterol that removes eggs from their diets and makes a marked, identifiable improvement should become eligible for a small incentive.
This would only be for the duration of the change and if a relapse occurs, the incentive is forfeited.
