49 and other squares

A couple of days ago, I saw the latest movie in the UP series: 49 Up. The UP series follows the lives of a fixed set of people, via a movie every 7 years. This "reality" series has successfully represented the characters and their evolution, together with the development of UK over the past 50 years. I was somewhat disappointed to see idealists, revolutionaries and the shy ones in their 20's, all turn more or less sentimental over their (grand)children in their late 40's. Relationships fall apart, people redefine themselves, and the 49 year olds look to the future through their children.

ps: My friend married the well-physiqued Mathematician who claimed his age was a perfect square and she mistakenly thought he was 36.
