Meet the people who speak many languages. How do they do it, and why?
Simon Calder meets people who keep learning new languages not because they have to, but because they want to. What motivates them? Situations like this - an immigrant hotel cleaner who is moved to tears because you speak to her in her native Albanian; A Nepalese Sherpa family that rolls about laughing in disbelief at hearing their foreign guest speak Sherpa. But do polyglots have a different brain from the rest of us? Simon travels to a specialised lab at the Massachusetts Institute of Technology, and undergoes a brain-scan himself, to find out.
