If you are going to buy this book, don't start by reading yourbirthday. Pick your birthday and four random dates and have a friendread them to you without telling you which date is which. Score howwell each description applies to you on a scale of 1-10 (1 lowest-10highest)I have done this with five people so far. No one has scoredtheir birthday the highest of all descriptions read. Two have scoredtheir birthday as 1 out of 10...It is a testament to thescientific illiteracy of our country that someone can make moneyselling this... How ironic you can buy it through your computer onAmazon in the most technologically advanced country on earth
