Reveal Your Weight or Pay

Apparently, employees of CVS pharmacies are upset over a new rule that they reveal their weight or pay an extra $50 per month in insurance premiums. It's understandable that the company wants to make sure its employees live healthy lives and decrease health management expenses, but not all health issues are weight-related.

Does the person who is average or underweight yet genetically predisposed to high blood pressure pay higher premiums? What about those with asthma and other allergies? I think the company's efforts are to be commended but that they're going the wrong way about it. What are your thoughts?
