Humans have been making music for thousands of years, but for Michael Mosley and our volunteer Matthew, the musical journey is only just beginning. Playing a musical instrument has been shown to strengthen your memory and lift your mood. It can even reduce chronic inflammation. Dr Sofia Seinfeld from the Open University in Catalonia tells Michael why it’s never too late to start making music, and how it can enhance your cognitive abilities by activating regions of the brain associated with motor co-ordination and the processing of emotions. Meanwhile, Matthew gets to grips with the ukulele to see if he can master a tune and boost his wellbeing.
