Query: A funny and insightful book!

This is an absolutely delightful book! It is full of wonderful and ironic humor which is both hysterically funny and insightful. The honesty and wisdom of Mr. Witte's observations (posed as a "birthday quiz") are oddly comforting to those of us who are near to either side of "F-Day"(Fifty!). I hope Mr. Witte continues to write in this vein. I highly recommend this book.
