He died, they think, from a heart attack as he was driving and turning a corner in his car. The car crashed into a 3 foot high wall; no one else was involved and they think it was quick. There will be a post mortem and probably a burial next to his wife.
That's the last of my grandparents now. He was the oldest at 92, and funnily enough the only smoker. My mother asked me if I wanted his wedding ring.
