We always think of the middle aged man in the brand new Porsche as the one looking for a partner who is younger than him. We picture Hugh Hefner or, god forbid, Woody Allen. But actually, nowadays women are breathing new life into the age difference dynamic. More and more, women like Madonna or Demi Moore are taking partners who are ten or more years younger than them. We've even named these hot and resourceful women after the intimidating predator, the cougar. These are women who have been around the block a few times and are now taking charge of their love life with a younger man. Of course, this still isn't as widely accepted as Hefner's antics, but it's definitely a sign of the changing times.
