Query: Lose 20 lbs. in one simple book!

Don't learn how to lose weight by reading some overpaid TV personality, or learn confidence from an over-caffeinated yuppie. Learn how to live happy and healthy through hard work, moderation, and frugality. Only learn from the best, Benjamin Franklin! Read now, and learn how to live your best life ever. This book has a confidence in man that I have never observed. For all the selfishness, laziness, and overall rudeness that exists today, this is, in my opinion, the most important biography of our time.
