Book excerpt: If you are among the more than 50 million North Americans who will turn 50 during the next 10 years, Fifty Things To Do When You Turn Fifty, Third Edition might just be the thing that enables you to approach the experience with optimism rather than dread. This is the third edition of our perennial bestseller and it's packed with artists, pundits, and experts who contributed essays offer a wealth of practical information. When taken collectively, the book comprises a veritable instruction manual for how to turn 50, everything from how to readjust your stock portfolio to how to readjust your underwear (to allow for more breathing room... wearing comfortable clothing is, after all, a privilege that you have more than earned by now). The underlying message is: relax, now that you're 50, you don't have to prove yourself anymore. Take care of yourself, get your house in order, and these will be the best years of your life.
