I think you will find, soon, that those people who have unapproved lifestyle habits (except sexual promiscuity, of course) will be on the outside of the healthcare world, looking in. Well, also excepting those who enjoy political power or favor, of course.
Nevertheless, one does need to wonder at least a little about a society that purports to “change the behavior” of its citizens, particularly if the “change” does not clearly lead to any societal or even individual benefit and presents no clear and present danger to anyone. Do we, like the giddy early Bolsheviks somehow think we are going to abolish illness and death by fiat or overblown optimism based on anecdotal science? Yes, studying well people will definitively establish…that they’re well.
It is well known that members of contemplative religious orders enjoy remarkably good health and long lifespans. But does that mean that the government should therefore impose Carmelite-like behavior on everyone? A single cup of vegetable soup for Thanksgiving, perhaps. Or perhaps instead a bowl of boiled nettles. After all, the inhabitants of the Gulag lived on that, didn’t they, and their BMIs were wonderfully low. And if the inhabitants of the Gulag smoked manure in the absence of tobacco, well, there are no statistics kept of the hazards of the former, so perhaps that can be permitted.
It truly does astonish me that in a supposedly free society there are so many who so readily revert to what is essentially a secular Puritanism, and upon such uncertain premises. If we can’t be allowed to be overweight, then what can we be allowed with any certainty? To follow the dictates of the state, one supposes.
