In sports there have been many other cases of seemingly impossible records which have later been broken. Some years ago it was unimaginable that people would ever pole-vault over fifteen feet, but today the record is over twenty feet. For many years it was thought that man would never break the four-minute mark for the mile race. But today it has become common for college runners to go faster. And then, many people thought that women never could, or should, run long distance races such as the marathon. Yet today it is common for woman to run the marathon faster than the fastest men of fifty years ago.
