eating habits
I doubt if the eating habits will stick with them for the rest of their lives, tastes do change.
It all comes down to self discipline, doesn't it? This is just another way of raising funds for government programs! We don't need more taxes, we need these "experts" to go away and study something more important, such as why the government spends way more than they take in (maybe too many studies paid for by government?), and why there are tax cheats and how to catch them, or people renouncing thier citizenship to avoid taxes...)
