"The British scientist who first linked smoking to lung cancer died yesterday, aged 92. Professor Sir Richard Doll suggested the connection in a 1951 study and confirmed it three years later. Dr John Hood of Oxford University said his work saved millions of lives. In 2001 Prof Doll caused controversy by saying the effect of passive smoking "is so small it doesn't worry me"."
The words of a respected expert in epidemiology with no axe to grind. Thanks Prof Doll and may you rest in peace.
