A proposed state law that allows health insurance discounts for improvements such as losing weight or cutting cholesterol could lead to a system where co-workers with the same coverage pay different premiums based on their health, The Denver Post writes. “People respond to incentives,” said Rep. Joe Rice, a Littleton Democrat sponsoring the bill up for debate at the Capitol. Critics of the proposal are skeptical. “It sounds wonderful and I believe in wellness, but once again I’m cynical enough to assume it’s going to be in the best interest of insurance companies, ultimately,” said Sen. Joyce Foster, a Denver Democrat who was one of two senators who voted against the bill when it passed out of committee last week.
