Ageing and our Senses

Does our sense of taste change with age? How are horrid and pleasant smells decided by our brains? Is it harder to urinate when you're older? We tackle these time-sensitive questions in this week's show as well as find out how de-caffeinated coffee is made, whether caffeine is bad for us and how we acquire the bacteria that live naturally inside us. Plus, we investigate whether love can rule our brains! Like this podcast? Please help us by supporting the Naked Scientists
