Exercise as You Grow Older

The authorsa mother, her daughter and granddaughtermaintain that old age is no excuse for being unfit and that even people who are already healthy ""could, if they would, be more active and feel better about themselves and be even healthier, too.'' Interspersed with stories about themselves, the authors suggest exercises for beginners and for people with limited strength and flexibility. There is, for example, the ``finger spread,'' which consists of extending arms horizontally, making a fist and then spreading the fingers. Directions are clearly written and amply illustrated. The book is also notable for its common-sense approach. On pacing, the authors write: ``Don't compare yourself with anyone but yourself.'' (September)
