The Getting of Wisdom

None of us are getting any younger. As our bodies show signs of wear, so do our brains. We get forgetful, are confronted by new ideas and perplexed by new technologies. The world appears to be moving way too fast, as we sink into memories of the good ol' days. Eminent neuropsychologist and author Elkhonon Goldberg argues we have no excuse. His message - make your brain sweat if you want to enjoy your mental life to its fullest. And his suggestion is that the two hemispheres of our brain age differently as we wise up.
