I read the headline and thought, "That's weird, Gates isn't really interested in things that just save money these days." And sure enough, from the article:

> "...may help end almost 500,000 infant deaths and save $233 billion annually in costs linked to diarrhea, cholera and other diseases..."

So I guess that's Bloomberg for you. 233 billion dollars is a way more interesting lede than a mere half a million lives.
