 Look, I mean, bad news is news, and we have to cover the terrible news. But I think we don't often enough provide the context, the trajectory of improvement that underlays that. When I first began traveling the world in the early 1980s, especially in sub-Saharan Africa, there was so much blindness everywhere. That really left a deep impression on me, from river blindness, from trachoma, from cataracts, et cetera. And now there is so much less blindness.
