Sacred Haven of Debauchery

I wouldn't feel any worse than I do now. I would simply be unaware of the benefits that exist in our time, and I would be fine without them.

I don't think you would be fine. You certainly wouldn't know about these benefits, but you would still feel the pain of bleeding gums and falling teeth. And the pain in your back after a full day in the field/hunting – that too. And the grief from your loved ones dying from a cold, I think you would be able to comprehend that as well.
