I have no idea what you're talking about. Disease is less prevalent now than it has ever been in history. People live longer and better lives than ever before.

While I fault the parent for lack of nuance, I fault you for the same.
"Disease" is a complicated thing which has many dimensions. What you're pointing out is that the low-hanging fruit are sorted and that's great! Parent was saying [edit: I assume] that chronic diseases were less frequent and we have epidemiological evidence that was the case.
