Henry remembers the day well. It was a day that would change his life. He was sitting at the kitchen table, watching his ten-year-old granddaughter, Sophia, do her homework. She had asked him a question about history and was now 1 him with big brown eyes, waiting for an answer. Henry looked at the kettle and then out of the kitchen window. Henry can still hear himself say, "I'm sorry, my dear. I don't know."

Henry had spent forty years working as a librarian in a school. He was now 2  and spent his days looking after Sophia. However, he felt that he should be doing more with his life, though he was in his seventies with grey hair and 3  wrinkles in his forehead （额头）. As Sophia continued her homework, he read an article in the newspaper about the health 4  of older people going back to university. The article said that it kept the brain 5  and helped prevent loneliness. He made the 6  there and then. The next morning, he would go to Birkbeck, University of London and take a 7  in history. 

After four years, Henry got his degree in history. "8 the course has given me such a sense of achievement," he says. "It has also made me 9 about doing all the other things that I've never had the courage to try before. It's 10 too old to learn."
