London, My city, My challenge

This story you are going to read is true. It is the story of a man who was politically powerful, very rich, and a philosopher too.  You might think such a man had the perfect life with no lack of anything and not denying himself any pleasure.

Some years ago I heard this story on television.  It goes as follows: A young girl named Sophia had been taking care of her mother Phisis for many years, because she had a back injury.
