I think I'm starting to understand Medicine

I've always been puzzled at how much "health research" money goes into developing drugs and understanding the biochemistry of the body. Shouldn't we spend more money thinking about how to get people to actually take up our current medical knowledge to use--getting people to exercise more, actually take their pills, eat healthier, and practice mindfulness and other good psychological practices.

This letter to the editor to the NYTimes helped me understand why we don't:

Re “Yes, Economics Is a Science” (Op-Ed, Oct. 21): ...
It is good to hear that economics is entering a phase when rigorous analysis and empirical testing will become the norm. . . . Scholars of physics, chemistry and medicine can study the movement of atomic particles or lab mice without any concern that the particles and the mice are interested in the results. . . .

Medical research isn't about understanding how to make people healthy, it is about understanding mice!
