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.

Madam Curie started her research that led to a Nobel Prize when she was 28. Einstein was 26 when he 10 his world-changing theory of relativity. Well, 11 of that. Yet I wondered if those “best years” were true in other 12 .

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.

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.
