How can meditation affect aging and memory?

The Journal of Memory and Cognition reported college students meditating displayed significant improvements in memory performance over a two-week period on a perceptual and short-term memory test. The International Journal of Neuroscience published findings showing meditation reverses the aging process. Individuals practicing meditation for more than five years were physiologically 12 years younger than their chronological age, as measured by reduction of blood pressure, and better near point vision and auditory discrimination. Short-term meditators were physiologically five years younger than their chronological age. The study controlled for the effect of diet and exercise.
