Yesterday evening I was watching the evening news on TV. The news was about a prize for scientific discoveries. The ______ said something that caught my ______. “All great discoveries,” he said, “are made by people between the ages of 25 and 30.” Being a little over 30 myself, I wanted to ______ with him. Nobody wants to think that he has passed the age of making any ______. The next day I went to the public library, spending several hours, and ______ to find the ages of famous people and their discoveries. The announcer was right!

First, I looked at some of the ______ discoveries. One of the earliest, the famous one that ______that bodies of different weights ______ at the same speed, was made by Galileo when he was 26. Madam Curie started her research that led to a Nobel Prize when she was 28. Einstein was 26 when he ______ his world-changing Theory of Relativity. Well, ______ of that. Yet I wondered if those “best years” were true in other ______.

Then how about this in ______? Surely it needs the wisdom of ______ to make a good leader. Perhaps it does, but look when these people ______ their careers. Winston Churchill was elected to the House of Commons at the age of 26. Abraham Lincoln ______ 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 30? After 30, I ______, most people don’t want to take risks or try new ways. Then I thought of people ______ Shakespeare and Picasso. The ______ was writing wonderful ______ at the late age of 50, _______ the latter was still trying new ways of painting when he was 90!

Perhaps there is still hope for me.
