I wonder if the idea of opening up a whole new audience to 60-year-olds looking to make sure their brain cells don't die off is a sustainable form of entertainment. Maybe they got it right because we are all an aging population in Western markets, but I somehow think as a form of entertainment that won't be the case," he concluded.
