This is basically how it went for the majority of human life when somebody asks about "what did they do about XYZ?" in regards to health.

Well, either they lived with it, or they died in 90% of cases.  Modern medicine is a thing of beauty that we take for granted, go back 150 years and unless it was a very common and well understood problem (e.g. broken bones, cuts and other basic physical trauma) if your body couldn't fix it's self you probably died.
