You can try to educate people, encourage people, have publicity programs that try to sell healthy living as "cool" and all that, but you can't punish people that don't succeed.
How could you establish criteria? 10 pounds overweight is OK but at 11 you pay more? What if you gain some weight while recovering from two broken legs? What if you're underweight due to an eating disorder? What if you quit smoking 5 yrs ago? 10 years ago? 15 years ago? (That would be me btw) 1 beer a day OK? How about 2? 3? Wine OK? Who measures your consumption? Etc. etc.
Poor lifestyle habits also overlap with genetics. Keeping the two separated would probably be troublesome. Some folks should never be in the sun at all, period. Others tolerate it much better. What would the criteria be? If you have fine red hair, freckles and fair skin we'll double your insurance rates if we catch you outside without being fully clothed and wearing two gallons of SPF 50 sunscreen?
How do you check on people without becoming big brother or impacting personal rights and freedoms more than our current Homeland Security?
How do enforce if enforcement might involve higher costs for people who can't afford it?
I understand the temptation to conclude that just obvious violations would get tabbed......such as being a heavy smoker. Or being obese. But I still wonder how to set criteria, deal with exceptions, monitor without violating privacy and enforce without inappropriate harsh punishment such as denying coverage or witholding care.
And I share the frustration. People display unhealthy life habits yet get medical coverage for the same price as folks with healthy habits. Kinda sucks. But I really don't think there is a viable solution.
Anyone know how it works in Canada, UK or Australia?
