"Useful strategies to keep the middle-aged mind limber. Everyone draws a blank now and then, but it was happening to Ramin with disturbing frequency. The author doesn’t pretend to be scientific in her sampling of cognition-boosting approaches, but she reads the relevant literature, consults with leading practitioners, and engages in the therapies as participant and observer. She burrows deep in sleep studies, explores the latent effects of mildly traumatic brain injuries, learns what the brain likes to eat, takes the pharmacological route, grazes on meditation and thoroughly investigates hormones, genetics and dementia. Ultimately, Ramin asserts that steady mental stimulation (memorize poetry, learn ballroom dancing), physical activity and social interaction are all key to keeping the brain young. A wholly encouraging plan for mental fitness."
