Judith Horstman, a Sacramento, Calif. freelance, practices what she advocates and keeps her brain busy writing about the brain. Her latest book taps into the most current research to unearth secrets about the brain as it ages. Neurologists and psychologists have discovered the brain from ages 35 to 65 years is much more elastic and supple than anyone previously realized. Far from disintegrating, the aging brain can continue to develop and adapt in many ways. Happiness increases, Horstman maintains, and while our short-term memory may not be what it once was, we gain better control and develop superior neural networks — something that was entirely beyond us when we were younger. The book offers new insights on how even an aged brain can repair itself, and the best strategies for keeping your brain healthy. It also shows how aging people can still achieve new level of intelligence, acquire new skills, perspective, and productivity; dispels myths about the aging brain-improvement; and explores what we should be aware of and what to expect as our brains mature.
