In this week's New Scientist is a review of a book entitled Monkeyluv: And Other Lessons on Our Lives as Animals by Robert Sapolsky. As part of his quest to uncover why we act as we do, he sought to determine at what age people close off to new experiences. This came about in part during interactions with Paul, a temp "whose eclectic taste in music gets 40-something Sapolsky wondering why the soundtrack to his own life has shrunk to a couple of Mahler symphonies and a trusted tape of Bob Marley's greatest hits."
His answer?
( Robert is a boring old twit? )
