He's a legend of Formula 1, a three-time World Champion who fought to make the sport safer. Sir Jackie Stewart's good work continues today with his charity Race Against Dementia.

Sir Jackie joins Christian Hewgill to answer your questions on how F1 has changed since the 1960s and 70s, the great drivers of the past and how F1 cars and racetracks have become safer over the decades.

Lady Helen Stewart, Jackie's wife, was once his timekeeper. She stood at the side of the track with a stopwatch to record his lap times. In 2014 they learned she has dementia, a brain disease which can affect memory, thinking and behaviour. Sir Jackie explains how his charity funds research to find a cure.

The global charity, founded by Sir Jackie Stewart OBE, funds pioneering research into the prevention and cure of dementia. Find out more at raceagainstdementia.com
