In this PodCast Clive discusses with Guest Millennial Laura the Humble Toothbrush. They have been around for thousands of years in some form with the modern version being a simple and familiar plastic brush. But why is it that 23 million people in the UK now use electric toothbrushes? Do they really clean your teeth better or have we all been persuaded by the "toothbrush wars" as the two giant multinational companies that make them tell us that we must have one and so are spending up to £2 Billion a year on them? And why would anyone spend £340 on a top of the range electric toothbrush because it has Bluetooth? Clive and Laura have the answers!
