Read the text about the people coming to retirement. Mark if the statements below are true or false.

Retirement – surely it’s a golden age when you can escape the daily grind of work and spend your time doing gardening, taking holidays and chatting with friends? Not for everyone. Some people love their work so much that they stay on into their 70s, 80s and 90s.
The factory worker
Dorothy Beckett, 93, has been working in a cake factory in Yorkshire, UK for more than 56 years. She works a 40-hour week, putting cakes in boxes, together with people who are 70 years younger than her. In 1945, aged 36, Dorothy set up the factory with her husband, Fred. Now, the business has a £4m annual turnover. “I’ve never wanted to retire,” she says. “It would be the end of me”.
The car dealer
William Spencer wanted to be a lawyer. But when he discovered that he didn’t have the right qualifications, he studied accountancy at night school instead and got a job in a car sales showroom. That was 72 years ago, and he is still there today! “I’m paid for my experience,” explains William, 91. “I help the young ones to sell. I advise the staff, introduce customers, arrange special deals, deal with problems, and make sure everyone is happy.”
The banker
“In the past year I’ve travelled to London, Paris and Milan for work,” says Gerald Lilley, sitting with a poetry book on his knee in his apartment in New York. “I’ve been to London three times, to Japan twice and to China, well, lots of times. When I’m not travelling, I like to be in the office every day at about 9.30. And I tend to leave at around 4.00 p.m. Mr Lilley is 94, and is senior advisor at one of the big investment banks. He finds the flights more tiring nowadays, especially after long days in meetings. “I suppose it’s my age,” he says, “but I have my evening to relax, have a drink and read German, French and English poetry.”
