According to the journal Nature, the elderly can significantly increase their cognitive skills by simply developing a regular walking regimen. Of the 120 sedentary, elderly individuals tested, those who increased their stamina by walking three times a week, between 45–60 minutes each time, were more adept at switching mental skills quickly than those who aborted walking in favor of stretching and toning. Such news should be received favorably by many drivers, considering those quick-thinking skills are the same needed when operating a vehicle.
