Dr Glenn McConell chats with Emeritus Professor Michael Gleeson from Loughborough University, England. He is the biggest global name with many decades of research examining the effects of exercise and diet on the immune system. Exercise is beneficial for the immune system unless it is undertaken at a very high /elite level. A very interesting chat. Twitter: @profmikegleeson
