Between high infant mortality
The constant threat of starvation from a bad harvest due to bad weather
City and town rivers that acted as open sewers for the feces and urine of thousands of people.....as well as the dumping ground for butchers and tanners..........one can only imagine the stink
Unpaved streets where a few weeks of rain would result in all of the feces, urine, animal entrails, rotting animal corpses and animal manure been flushed into the streets
No anesthetic in surgery nor qualified surgeons to do surgery on you. If you had a toothache, your local barber would pull it out of your mouth with a plyers and without anesthetic........ Surgical procedures also often resulting in death due to infection and lack of understanding about bacteria.
Constant threat of plague and other terrible diseases....... including simple things today that can be medicated resulting in death.
Very basic diet of vegetables and black bread with meat and white bread been luxuries only the nobility could afford.
And much more.
Don't think I would have fancied been around in Ye Olde Medieval Times..... though I'd imagine given that they only drank beer instead of water, it might not have been that bad after all.
