Good news scientifically confirmed! In episode 1 of series 8 of the popular BBC series on health, Trust Me, I'm a Doctor, Dr Michael Mosley and his team conduct a four-week experiment on a group of language learners. The results of the test demonstrate that learning a language can make a significant difference to your mental abilities. The effect was most pronounced among older people. In the words of one of the scientists conducting the study, "learning a language is always a very good investment for life at any age."
