This slim volume is one of the best self-help books I've read. Instead of being filled with cheer-up nostrums, it offers a pragmatic, face-reality view of old age, as a time of diminished capabilities that can be worked around. It is permeated with Skinner's behavioralism, though not labelled as such until an appendix that maps the text's plain-spoken simplicity to technical terms of behaviorism. Its central precept is both devoid of sentimentality yet oddly comforting, for it puts the power to mitigate old-age's drawbacks within the individual's power: "In all these examples [of coping with, defeating, or succumbing to, the drags and diminutions of old age], what people feel is the by-product of what they do and of the circumstances under which they do it. Instead of trying to feel differently by some act of will, you do better to change what is felt by changing the circumstances responsible for it." ( )
