Book excerpt: Americans enjoy longer lives and better health, yet we are becoming increasingly obsessed with trying to stay young. What drives the fear of turning 30, the boom in anti-aging products, the wars between generations? What men and women of all ages have in common is that we are being insidiously aged by the culture in which we live. In this illuminating book, Margaret Morganroth Gullette reveals that aging doesn't start in our chromosomes, but in midlife downsizing, the erosion of workplace seniority, threats to Social Security, or media portrayals of "aging Xers" and "greedy" Baby Boomers. To combat the forces aging us prematurely, Gullette invites us to change our attitudes, our life storytelling, and our society. Part intimate autobiography, part startling cultural expose, this book does for age what gender and race studies have done for their categories. Aged by Culture is an impassioned manifesto against the pernicious ideologies that steal hope from every stage of our lives.
