And the big news about meditation for older folks comes from a study at UCLA that finds meditation slows the usual shrinkage of our brain as we age: at age fifty, longtime meditators’ brains are “younger” by 7.5 years compared to brains of nonmeditators of the same age.27 Bonus: for every year beyond fifty, the brains of practitioners were younger than their peers’ by one month and twenty-two days.
