As the boomers age, they are focusing less on acquiring "stuff" and more on great experiences, creating special memories with family and friends. The most affluent boomers own multiple homes, more clothing and jewelry than they can wear, more luxury products than they have room for and have less energy and time to care for and manage all of these material things. Boomers, though retiring later, are spending more and more of their time savoring and enjoying their "golden years."
