You know what, it makes 0 difference, my uncle was overweight, smoked cigars every day and drunk like fish, he lived until he was 102, my aunt was thin, healthy and active, she died when she was 30, its all fate. And hospitals are not full of all fat people, there are people there of every size.
Drinking isn't good for you, smoking ext, fat wont get you any sooner, you could be stick thin, walk outside and get his by a bus.
That would be very discriminative, they don't have the right to tell people how to live their lives, they can't say, you're fat loose weight if the person doesn't want to. That's like saying, booze is unhealthy so we wont sell you a bottle of wine. you don't have that right, it's against a person's human rights. You can't force people to conform, thats the same as forcing everyone to be the same religion and besides, how can they tell the lazy fat people from those with medical problems?
