Sir Nicholas Winton is a good advertisement for old age and a particularly powerful promotion for humanity.
There he was at Liverpool Street station at age 100 bright eyed and alert welcoming some of the 669 refugee Jewish children and their descendants whom he had helped to save from the clutches of Hitler and Nazism 70 years ago.
In the midst of all the horror and despair of that awful episode in world history there he was a young British Shindler making a massive difference as an individual.
Remarkably he even kept this all quiet from his wife and family for 40 years until his wife discovered some papers in an old briefcase in 1999.
The man is a towering hero.
