Sir Stanley Matthew went to an egagement where the Queen of England was present when he was at the end of his career but he played well into his 30's and even 40's. He was leaving the egagement at 9:00p.m. and was questioned by the Queen as to why he is leaving so early. His answer was that he had a game the next day and he needed his proper sleep. This is dedication. And one of the reasons why he was able to outrun players half his age.
