Whole Foods to offer greater employee discounts to people who are skinnier, have lower cholesterol and blood pressure

Keep in mind that the guy who runs Whole Foods is a right-wing Republican nutjob. His latest brilliant idea is to give employees greater in-store discounts if they have lower blood pressure, cholesterol, body mass index, and don't smoke. The idea is interesting, but also a bit unnerving. I have low blood pressure (good low blood pressure), but it's not because of anything I've ever done. It simply is. I've also been relatively skinny most of my life, again simply because I am. Why should I get more employee benefits for things I had zero control over? And an even bigger question, what does the Americans with Disabilities Act have to say about employers who decrease employee benefits based on their physical maladies (high blood pressure and high cholesterol)?
