What do you want to know about medieval hygiene?

Ladies and Gents, I have a question for you.
You all may or may not know that I have declared this "Get the Darn Complete Anachronist Manuscript on Medieval/Renaissance Hygiene done" Month.
So, here's my question for you, not only those who have followed the blog but those who are just joining us:

What sorts of information would you want to see /read about in this CA?

Thanks!
