Harriet Kelly has one word to describe the day she stopped driving four years ago: miserable.
"It's no fun when you give up driving," she says. "I just have to say that."
Kelly, who lives in Denver, says she was in her 80s when she noticed her eyesight declining. She got anxious driving on the highway, so decided to stop before her kids made the move for her.
"I just told them I'd stop driving on my birthday — my 90th birthday — and I did. And I was mad at myself because I did it," she says, laughing. "I thought I was still pretty good!"
