This classic work is the result of a forty-year study of adaptive mechanisms in the life cycles of 268 subjects. Why do some of us cope so well with the portion life offers us, while others, who have had similar advantages (or disadvantages), cope badly or not at all? Are there ways we can effectively alter those patterns of behavior that make us unhappy, unhealthy, and unwise? Copyright (C) Muze Inc. 2005. For personal use only. All rights reserved.
