For at least a millennium, the heart of Britain's commercial and financial industries has been the City of London.
The City is not the large metropolis we know as London. It's much older and smaller. Many call it the Square Mile, though it's not square and a bit bigger than a mile. It's the home to big banks, medieval alleyways and St. Paul's Cathedral. And, for all those centuries, the area has had the same local government with an unusual name: The City of London Corporation.
Some famous writers, painters and musicians have done some of their best work in their later years — impressionist Claude Monet, for one. But at the North Hollywood Senior Arts Colony, older people are proving that you don't have to be famous — or even a professional artist — to live a creatively fulfilling life in old age.
With a fully equipped theater and painting and sculpture studios, there seems to be rehearsals or exhibitions of some sort going on here all the time.
Brothers Paul and James Bizzaro, both in their 80s, spent their childhoods living in a house right behind the Statue of Liberty. Their family moved to the same small island in New York Harbor as Lady Liberty 75 years ago this summer, not long after their father, also James, became a guard at the statue.
When the Bizzaros moved to what's now called Liberty Island in 1937, Paul was 8 and James was 6.
"Half of the island was for the visitors. The half that we lived in, we had that whole half to us," says James.
Why does anyone buy Bayer aspirin — or Tylenol, or Advil — when, almost always, there's a bottle of cheaper generic pills, with the same active ingredient, sitting right next to the brand-name pills?
Matthew Gentzkow, an economist at the University of Chicago's Booth school, recently tried to answer this question. Along with a few colleagues, Gentzkow set out to test a hypothesis: Maybe people buy the brand-name pills because they just don't know that the generic version is basically the same thing.
