Do you think that the period from 1350 to 1750 was a period in medicine of mainly change or mainly continuity( continuing old method) ?

Dark ages: Let me use leeches get rid of your bad blood!

Reinassiance: Let me dissect this corpse, to help find out how to help. (Helps find better ways to get rid of diseases, without killing you by leeches)

Industrial era: Let me shove you into a major city with millions of others, in a small home! (Major wide spread epidemics forcing governments to react, this is later but whatever)

The medicine from 1350-1750 had changed drastically, you no longer had to fear of dying as often, as the medical procedures weren't as insane.
