What do All-You-Can-Eat Buffets and Health Insurance have in common?

As somebody who loves a good (and sometimes bad)  all-you-can-eat buffet, I consider myself somewhat of an expert on the subject.  I even considered majoring in "Chinese Buffet" while in college.  Sadly, there is little demand for a buffet expert.  I always wondered how buffets actually make money.  It turns out that many economists have asked the same question.
