PIH was still small then, in the first years of the new millennium, and yet it was already creating vivid proofs that diseases that could be treated successfully in the developed world could also be treated successfully and economically in some of the poorest, most difficult settings imaginable. That was the moving thing for me, seeing the proof. There is all the difference in the world between passively witnessing misery and witnessing people at work trying to relieve misery.
