How to ensure that people live unhealthy lives?

Why not reward them for it? I was reminded of that by a story today:

Canada's two largest airlines must give disabled and morbidly obese passengers an extra free seat on domestic flights, beginning in January, after the Supreme Court of Canada refused Thursday to consider the carriers' appeal to a federal order. (In the Calgary Herald)

On the one hand I don't have a problem for there to be accommodations for the disabled or for those obese due to glandular issues. On the other hand I have a large problem (pun intended) with accommodating those who are obese due to lifestyle choices.

Of course, Britain has managed to do things in a slightly more ridiculous fashion:

Overweight parents will be paid to walk their children to school under plans to tackle the obesity epidemic. Those who attend keep-fit classes, weight-loss clubs or even go for a run in the park would also be eligible for rewards. They will collect points on supermarket-style loyalty cards which would be redeemed against healthy food, sports equipment or gym sessions. (In the Daily Mail)

I've been trying to find back the original article that I read on this plan a week or two ago, which had a few more details. Basically the government will pay you if you're obese, to try to get you to eat healthy foods and exercise. Of course, how much incentive is there then to lose weight when the payments stop as soon as you're no longer obese.
