Sound can have a very powerful effect on how we feel about the world and Nigel Marven is on a quest to track down the sounds which have the most powerful emotional effects on us. Balance is our true sixth sense - it enables us to sense how our bodies are moving around in the world and keep us upright. There are only two kinds of animal that spend their whole lives performing the tricky balancing act of walking on two legs – humans and some flightless birds, like ostriches.

In this series, Nigel goes in search of the biological roots of our senses and uncovers the evolutionary reason why particular sights, sounds, smells and tastes have such a powerful effect.
