You know, I was laughed at when I was doing my degree for being interested in social history (although it was on the curriculum!!) but there are so many questions: how did people clean their teeth before there was toothpaste?
Salt, bicarbonate of soda, ash, crushed shells
what did they use instead of soap?
Clay or ash mixed with fat, depends how far back you want to go the Romans used oils which they scraped off with a strigil.
what did they do when they got sick?
Used herbal remedies, many of which form the basis of todays medicines
had babies?
Childbirth was well understood in earlier times we must remember that the country was an agricultural economy and birth was a common sight.
Unfortunately hygiene was not given a high priority and so many babies died.
Pain relief would not normally be given but alcohol may have been used at times.
how did they go to the loo before plumbing? We just do things today without even thinking most of the time about the things we're using, or wondering what we'd have done a few hundred years ago. And I think not thinking is a Bad Thing! 
The same way as people go to the loo today if caught out in the wilds of the country, leaves grass etc. may be used to replace paper.
