INFJ, here (?).. 11, 50, 12, 67.. I notice that I am indeed in good company, I think.. :)
I'm an INFJ, too, but I was a little creeped out by the list of famous people that are INFJ - Shirley McLaine! Jimmy Carter!!! Carol Moseley Braun!!!! YIKES! How the hell could I be on the same list as those people?!?
I've worked most of my life as a retail store manager.
