This is interesting: aging adults can boost their memory just by taking a walk.
“With a limited investment of time and effort you can produce fairly dramatic improvements in memory and brain health,” senior researcher Arthur Kramer, of the University of Illinois at Urbana-Champaign, told LiveScience. “You can roll back the clock about two years.”
Physical exercise — it doesn’t have to be aerobic — seems to grow a structure in the brain called the hippocampus at a time when it normally decreases.
Maybe that’s why the Scriptures describe our life as a “walk.”
