If you got sick more than 300 years ago, you are not going to have a great time. There are many weird treatments that we know wrong and cruel today. First, when the pledge struck Europe, doctors just poke at the patient's bubble on their skin, which will infect others. Another example of cruel treatment is to drill a hole on a headache patient's head and said to let the bad thing out, but this treatment will actually leave a permanent mark behind, and due to the bad medical technology back then, people usually die from this. So anyway, you don't want to be sick back then.
