In histories of the period before modern medicine, people were often “sickly” in some fashion or another.

That’s been much less true the past hundred years or so. With a few exceptions (terrible accidents, horrific war injuries), if whatever you had didn’t kill you, you probably got entirely better.

Looks like I was right:
