Want to find out if you have a special aptitude for learning languages? The UK's Channel 4's  popular, new series, Hidden Talents has created a slew of specific self-marking online tests designed to tease out innate abilities and this week they've added a language aptitude test. Give it a go when you're feeling brave, but don't worry if you don't score highly, as we've spoken to several people who didn't do well in the test but nevertheless are happily and successfully making a living using their language skills.
