If genetics is causing your obesity then that would be an underlying issue. Read what I said before throwing a tanty. I never actually said that ALL obese people were stupid, lazy, over eaters. I am obese myself (with medical reasoning, not just because I like to eat), so I am not about to do say that so generally. NOR am I about to claim some kind of disability, which is the cover I am talking about.
The difference between you and this woman would be that you did something to make a change for the better. She is essentially eating to kill herself, and I do not see why ANYONE would do that, nor do I see why she deserves a) any kind of disability allowance/welfare/food stamps etc and now that you mention it, I don't think she'd deserve any kind of insurance EITHER.
