What would happen if you ate nothing but fast food for an entire month? Filmmaker Morgan Spurlock does just that and embarks on the most perilous journey of his life. The rules? For 30 days he can't eat or drink anything that isn't on McDonald's menu; he must wolf three squares a day; he must consume everything on the menu at least once and supersize his meal if asked.

Our lifespan is increasing by 2.5 years every decade - and a third of all babies born today can expect to live to 100. But living longer can come at a cost. Old age itself brings with it a range of debilitating illnesses, many of which are the result of accumulating damage during our lifetime. Three diseases in particular have become the main killers in the developed world - cancer, heart disease and dementia.
