阅读短文,回答问题 How old is"old"? The answer has changed over the years. Two hundred years ago , you were old at 35. That was the average life span(跨度; 范围) then. At the turn of this century, as medical knowledge improved , the average life span increased to 45. In 1950,70-year-olds were really old. Today, a healthy70-year-old is looking forward to many more active years.
So, how old is old? Once an unknown writer wrote, "Youth is not a time of life but is a state of mind. Nobody grows old by living a number of years; people grow old by giving up their goals."
Old is a point of view. Alice Brophy, when she was with the New York City commission for the Aging, said , "It makes me angry when people say, 'Gee , you look young for your age!' What does that mean? Is there a model that you' re supposed to look a certain way at 65 and 75 and 85? You know you can die old at30 and live young at 80."
