How did HIV originate? Why does anaemia occur more often in Africa? Do growing pains exist? We take on these infectious questions as well as find out how limescale remover works, how rainbows form and whether all objects expand in heat. Plus, we investigate if humans can get stronger under stress and reveal how much water we should drink for a healthy body. Like this podcast? Please help us by supporting the Naked Scientists
