Sport of Hard Knocks

Could sports such as rugby and football, great for fitness and socialising, actually be creating conditions for dementia-like symptoms to set in on the brain for some people? John Beattie investigates how the innocuous and not-so-innocuous knocks taken by players are being shown to potentially have debilitating effects years later, unknown to the former players.

Taking the research from the crushing sport of American Football as a starting point, John discovers what lessons could be learnt for people who play rugby, football and other sports.
