The more I learn about a time period, the more I want to know but the less I want to visit. Using powdered rabbit head for tooth cleaning doesn't appeal to me, but for the Tudors it was either that or honey.
I'll stick to minty-flavored chemicals.
More than the day-to-day oddities, I'd object to the overall likelihood of pain and death at an early age. The government, the entity formed to care for its people, could brand, maim, imprison, or even kill a person pretty much at the whim of those in power. Nobles lived in a stew of plots and counterplots where brother betrayed brother and wife testified against husband. Yeah, I know we have such perfidies, but nobody gets his head chopped off at the end.
Then there's the whole lack of medical help. If a person could afford a doctor, unlikely as that was, he was more likely to hurt the patient further and even contribute to his death than to heal. Example: you're having eye trouble. The doctor puts powdered dog feces in your eyes. Think you'll be seeing the sunrise next week?
I suppose there were compensations. No speeding cars, no one sharing his inner thoughts with the world on a cell phone in the checkout line, and true darkness and quiet at night for better sleeping. I love imagining what it would be like, but you can keep your time machine. I'm too used to a real bed, sugar in my coffee, and central heating. Besides, I'm sure I wouldn't understand most of what was then called English.
