this is a fun book that offers much enlightenment about stuff that you thought you knew, but will be surprised to discover the true facts. it's entertaining to read and your curiosity for knowledge will be satisfied. i'd buy more copies and give it away to all of those who think you know it all! don't forget to keep one for yourself! good value too.
Got this for my 'smarty pants' step dad on his birthday.Its a great read and pretty informative, and knocks you down a couple pegs because after reading the question, thinking you know the answer, then reading the true answer, you come to realize you arent as smart as you pretend to be ;)
