Some nice ""it's-okay-to-be-40"" peptalk, negated by recommendations for a regimen that could take hours every day and form the focus of a life. Sommers' boost includes descriptions of how various ladies have approached their middle years--from working woman Diahann Carroll to the Baroness de Rothschild, who lives for her husband. (Best, though, is Germaine Greer--""who at forty-six was told during a television interview that she did not look her age, and replied that this was the way forty-six-year-old women look now."") There are also brief, reasonable tips on diet and exercise. But the bulk of the book involves ""problem-solving"" with make-up (to correct ""droopy underbrows"" and ""drooping nose tip""); trying eyeglasses with tinted lenses, as a fashionable camouflage; and--in meticulous detail--plastic surgery, massage, hair dyes, spas. Forty-plus is wonderful, natural, confident, says Sommers; but use these techniques to cover-up all the age-related flaws.
