    One of Scotland's most active centenarians ( 百岁的人), Lady Morton, drove for nearly 80 years. She loved driving and spent the war years as an ambulance driver for Bangour Hospital. Aged 100 she was still driving around Edinburgh, up to Perthshire and elsewhere — the oldest among all the drivers in Scotland. But she had her first ever accident several days after her 100th birthday — she hit a traffic island (a raised area in the middle of a road where people can wait until it is safe to cross) when she took her new car for a drive in Edinburgh.

    Lady Morton, who celebrated her 100th birthday in July, was given a car as a present. She talked about the accident happened that night. “I wasn't going fast, but I hit a traffic island. I couldn't see it, because it had no light, which I think was unbelievable and unreasonable. But I am all right and luckily my car wasn't badly damaged.

    Although Lady Morton had the accident, she didn't plan to stop driving.“Some people are just born to drive, and I think I am one of them. I've been a good driver since the first time I got in a car, she said. “I am musical, so I listen to sound of the car to know when to change gear (档位).

    Lady Morton bought her first car in 1927. The main change she had noticed since then is the traffic. “It's appalling. However, I don't mind it, because I am experienced, but I feel very sorry for beginners,” she said.
