translation.en: Now, "rational" is the dominant paradigm in public health, and if you put your public health nerd glasses on, you'll see that if we give people the information that they need about what's good for them and what's bad for them, if you give them the services that they can use to act on that information, and a little bit of motivation, people will make rational decisions and live long and healthy lives.
