Let"s face it—by the time you reach 40 there"s no getting away from the fact that you"re officially a grownup. So before you reach that landmark birthday, make sure those last few years of youth are (mis)spent wisely. After all, you"re unlikely to want to take up naked bungee-jumping after you"ve turned 40, are you? And, of course, if you"ve already hit the big four-zero, then this is your chance to look back and see just how wild your youth really was. Packed full of original ideas—some frivolous and fun, some inspirational and thought-provoking, and some sexy and downright illegal—this book is guaranteed to stave off middle age and spur you on to live life to the fullest.
