If you seem to be losing your keys with unsettling regularity, Mind Power might be the book for you. Gary Null, who wrote the bestseller Power Aging, is urging Baby Boomers to take control of their mental acuity by understanding and taking better care of their brains. Null encourages regular exercise, spiritual health through meditation and regular social contact and a nutritional plan packed with complex carbohydrates, soy products and organic produce. Null also examines the symptoms of several specific brain conditions, from depression to mental fatigue to Alzheimer's Disease, and shows how they can be combated. He includes a chapter of Mind Power Meals, or as he calls them, recipes for the mind.
