Query: Ageless Marketing by David Wolfe

There are a lot of people who know a lot of things about aging in America, and its impact on Marketing.Mr. Wolfe knows a lot of those things too, but unlike almost every other book I've read in this "new customer majority" arena he actually connects all the dots.After reading his book, I recognized the coming irrelevance of advertising as we knew it, and the dawn of a new time when everything you've learned previously in marketing, simply won't work.It may be a cliche, but if you read only one book about the mature market make sure that it is this one.
