The New York Times (8/12, Reynolds) “Well” blog reported that a study published last month in PLoS One suggests that “overall, ‘a small dose of exercise’ may be sufficient to improve many aspects of thinking and more sweat may not provide noticeably more cognitive benefit,” although it will improve aerobic fitness. The study of “101 sedentary older adults, at least 65 years of age,” revealed that “briskly walking for 20 or 25 minutes several times a week” appeared to be enough to help keep “brains sharp as the years pass.”
