Last evening I was watching the evening news on television. The news was about a prize for scientific 1      . I forgot what it was. The announcer,whose name was Ralph Story,said something that caught my 2      . "All great discoveries," he said? "are made by people be?tween the ages of twenty-five and thirty. " Being a little over thirty myself,I wan?ted to 3        with him. Nobody wants to think that he is past the age of making any discovery. The next day I happened to be in the public library and spent several hours looking 4        the ages of famous people and their discoveries. Ralph was 5      . First I looked at some of the 6        discoveries. One of the earliest discoveries,the 7        experiment that proved that bodies of different weight fall at the same speed,was made by Galileo when he was 26,Madam Curie started her research that 8        to the Nobel Prize when she was 28.        Einstein was 26 when he 9        his world-changing theory of relativity. Well,enough of that. Yet I 10        if those "best years" were true in other 11      . Then how about the field of 12     ?Surely it needs the wisdom of 13 to make a good leader. Perhaps it does,but look when these people 14        their ca?reer. Winston Churchill was elected to the House of Commons at the age of 26.Abraham Lincoln 15        the life of a country lawyer and was elected to govern?ment. At what age? Twenty-five.

  But 16        don't best years come after thirty? After thirty,I 17     ,most people do not want to take risks or try 18        ways. Then I thought of people like Shakespeare and Picasso. The former had wonderful works at the ripe age of fifty,19        the latter was still trying new ways of painting when he was ninety!Perhaps there is still 20        for me.
