For closers, both CBS and NBC chose media technology. NBC's George Lewis found that the elderly represent a growing demographic of videogame players. Some play memory games to keep mentally sharp; others prefer action. Nintendo's Wii is a hit at a Chicago retirement home where virtual bowlers never bowl alone--and do not have to lug around a ball.
On CBS, John Blackstone introduced us to Microsoft researcher Gordon Bell. Bell has equipped himself with a digital camera that takes a picture automatically every 30 minutes and a digital tape recorder that is constantly listening. Bell documents and archives every single detail of his whole life. Computer memory is so inexpensive, at $1 for a gigabyte, that he never trashes anything. He has a file of 50,000 family photos and his e-mail inbox has stored 110,278 messages. Bell plans a system to help people "record and recall their entire past."
