I was just listening to a This American Life podcast (don’t worry Canada, I listened to As It Happens last night on CBC Radio 1, so I’m keeping the Canadian content up).  The theme of the podcast was “the Sanctity of Marriage”, and the whole show was examining marriage and marriage-like relationships.  One of the most interesting segments involved a scientific researcher who has been studying the correlation between arguments, disagreements, and fights that married couples have to their chances of staying together or getting divorced.  He uses video cameras and heart-rate monitors to help him and his team observe the couples, and they follow them over an extended period of time, often many years.  The findings are very interesting, and there’s even some surprising (or rather, confirming!) information about gay and lesbian couples that stick it out!  So give it a listen!
