Earlier quoted context omitted.
Sorry, but if you think that we have equivalent fear of disease then and now, you don't know what life was like then. How many people did you personally know who died of disease as a kid? I knew one. (Cancer.) But this was a period where people would have 8 kids in the hope that 2-3 of them would survive to adulthood. And disease was the big killer.
Don't forget about a significant chance of dying or losing limb from any simple cut.
Just the things that are taken for granted as common sense now before they were.
