This looks right up LW's alley.

There is a question

I am a 3rd year medical student, and for the purposes of this question, let’s assume I have equal interest and ability in the various medical specialties. In order to create the greatest good for the greatest number of people through my work in medicine (i.e., the highest return to society), what specialty should I pursue? ... I’ve been looking at DALYs and QALYs associated with various medical interventions ...

And some answers, not all of which LW will like :-)
