It’s long been a jibe that someone is clever enough to walk and talk at the same time. But now it appears that being able to solve a problem while out for your constitutional could indeed be an indication of superiority. Researchers in the US have discovered the brain performance of some some older adults improves when they combine a cognitive task with walking. They asked a group of men and women aged from 62 to 79 to carry out the same task while sitting and walking. They found that some had brains that were able to adapt and improve while on the move, suggesting they were so called super-agers whose minds age more slowly than their bodies.
