It's amazing the things you can learn about from books, I don't just mean facts and figures. In a novel I was reading once I heard about a firm that made extract of lime aftershave. Actually they make a whole set of toiletries with that smell. I really dislike the smell of men's toiletries normally, so I got some for @brianhartgen to try and he's used it ever since. It's the only smell of men's toiletries I really absolutely love.
