Stewart won the world title three times at a time when many of his contemporaries were killed or seriously injured due to inadequate safety standards. Today’s drivers owe a lot to the courage he showed on and off the track. Among other changes, Stewart helped introduce larger runoff zones, better barriers, a dedicated medical unit, full-face helmets and seat belts. He still campaigns against dyslexia, which he was diagnosed with at the age of 41, and against dementia, a condition suffered by his wife, Lady Helen, while continuing to work in the paddock at the age of 85. years.
