In the last programme, von Hagens and Lee illustrate the process of ageing. To reveal the dread process for us all to see, the two scientists compare the bodies of two live models - an 84-year-old and a 24-year-old. Von Hagens then compares sections from the cadaver of a woman over 80 years old with the same sections from a much younger woman. By revealing the internal extent of ageing damage, von Hagens and Lee demonstrate the widespread effects of ageing and explain why we can't life forever.
