Gloria Heidi's the Hollywood equivalent of Candy Jones (see below) and she's got the sense to know that hats are out even if she's much too fad-and-fashion-minded as she converts her M.A.Ms (Middle-aged Matrons) into Ageless Women who won't have to count the years, or God forbid, reveal them. She's good on make-up (no bright eyeshadow embedded in your crow's feet), hair (the older you get, the more help you need), weight, exercise and health treated in greater detail than in the Jones book) as well as generally more conservative about radical cosmetic improvements and the menopause. She's cautious about estrogen therapy, but too sanguine on calcium. The finale (it's not all over) deals with sex and marriage. Abidingly glamorous people from Jackies Susann to Onassis appear along with Drs. Brothers, Rubin and Eric (sic) Fromm. Generally good advice pep-talked up, and a better buy than those ""chunky white plastic bracelets from the dime store"" at 69 cents each.
