I think it's what Dr. Tamblyn said: how do we align engineering science with social sciences and telesciences? It goes back to your previous question. If you project that we're going to be living until 90 years of age, it's what we do in our thirties—before we hit 40 years of age—that's going to make the difference.
One is, how do we make it easy for people to do the right thing in how they live, in what they eat, and in what they have access to and those kinds of things? That's where that alignment, if we do that....
Clearly, it's enabling policies that can help this. Is there some reason alcohol can cost the same amount no matter what latitude you're at, but fruit becomes exponentially more expensive the further north you go? That makes a difference in what people choose to consume, right?
Can we do something like that, which can reduce that inequity, that isn't going to happen through a health system—it's outside of the health system—and can help people be healthy? Those are the things.... I would focus on the 30-year-olds who are going to be getting to 90 years.
