What would have killed your 19th-century doppelgänger?

I had a very bad illness when I was just a couple months old. I don’t know what it was, but I was hospitalized, so very well could have died. Other than that, I’ve been pretty lucky, with mostly minor injuries. Of course, before the germ theory, who knows if any of those would have gotten infected and killed me.

Interesting to think about, though. Glad I live now.
