I am sorry about my lack of specifying in my last post.
What I am trying to ask is if a certain job must pay more for health insurance? I do not mean a stunt company that must pay incredible amounts of insurance for their stuntmen because they could die. I mean a company that has a higher than average heath insurance cost would try to get their obese workers fit because they cost more in health related issues than the average person. I have heard of companies providing "financial incentives" to workers who lose weight but is there a certain job you can think of (salesperson in-store, salesperson, store manager, etc...)?
