The announcer, whose name was Ralph Story, 2 something that caught my 3 ．“All great discoveries,” he said “are made by people between the ages of twenty-five and thirty.” Being a little over thirty myself, I wanted to 4 with him. Nobody wants to think that he is past the age of making any 5 . The next day I went to the public library, spending several hours, and 6 to find the ages of famous people and their discoveries.

Winston Churchill was elected to the House of Commons at the age of 26. Abraham Lincoln 16 the life of a country lawyer and was elected to the government at what age? Twenty-six.

　　But why don't best years come after thirty? After thirty, I 17 , most people do not want to take risks or try new ways. Then I thought of people 18 Shakespeare and Picasso. The former was writing wonderful 19 at the late age of fifty. 20 the latter was still trying new ways of painting when he was ninety!

　　Perhaps there is still hope for me.
