When the disease is cholera and other diseases spread by contaminated water,
the culprit seems pretty clear.

And right now we're seeing life expectancy in Africa drop because of AIDS. If
we developed a cure or vaccine for AIDS, and spent money to use it, life
expectancy would go back up. The world had lots of diseases as bad as AIDS:
smallpox, tuberculosis, cholera... gone now, and we live longer.

Off the top of my head, economists have decided they've been consistently
overestimating inflation for decades, and announced that the gap between
measured imports and exports over all countries has grown to 3%.
