I think you are right on with the MLC. I think it can strike at any age. As far as I can tell its more like you said an idenity crisis. The SO wakes up one day and says holy SH!t where has my life gone. Im not doing anything important I havent been anywhere, I dont have a great job making lots of money. That kind of stuff. Then they look around and say why is it like this. They see there S and go it has to be that person that has caused this and then they fall of the planet.
