Sound Body, Sounder-How working out Makes You Smarter

I found this article in the American Council on Exercise, Fitness Matters. I know what you are thinking.  What next?  But yes this is true.  Studies have proven that exercise will make you smarter.  The most recent study to verify the exercise-cognition connection, the results of which were published  in the November 2006 issue of the Journal of Gerontology, revealed that subjects who exercised  for six months showed an increase in the amount of specific kinds of brain tissue.  Kirk Erickson, Ph. D., a scientist at the Beckman Institute for  Advanced Science and Technology of the University of Illinois and one of the researchers who conducted the study, had one group of subjects walk three days a week for 45 minutes, while the control group were given non-aerobic stretching exercises.  After six months, brain scans revealed that the aerobic group had experienced a 2 percent growth in the prefrontal lobe, the site of higher-level functions such as goal-planning and multitasking.  The enlargement occurred as a result of the production and release of chemicals in the brain triggered by exercise. This goes to prove that exercise will improve mind, body and soul!
