I just finished reading an article in Time magazine that described a study that proved exercise improves memory. The article began by explaining that the memory loss we all experience beginning in middle age is normal (I’m happy to hear). Initially it was a research completed on rats that showed exercise produced new neurons in the brain. The research was then tried on humans, one hour on the treadmill four times per week proved to increase blood volume in the brain. Those same people went through memory tests before and after, and there you have it - better memory! It was aerobic exercise specifically, so get your heart rate up often.
