Packing For Mars: Mary Roach

I've been bothering everyone around me with facts about the space program for a couple of weeks now. I spent a good half hour describing the development of the space toilet to a friend at the pub the other day and it's all due to this book.
Mary Roach has tackled the subjects of sex, death and now space all in a hilarious but extremely informative style that always keeps me glued to the page and staying up to read way too late into the night. I can't recommend this book enough for those of us who want to be educated and entertained at the same time.
How cool is it that they made a commercial for the book? Get it here.
