Finally, over weight people should be required to pay a higher price for insurance.
Hope you're a vegan. Because the crazy BMI index doesn't apply to real people. I'm 6 foot 200 lbs with a 33 inch waist. I excercise daily. I would be considered over weight.
People who play foot ball, ski, surf or do any sort of other potentially dangerous activities, should also pay more. After all, what you do adds risk and costs as well, not just being overweight.
