Bart, Thanks to Sweens, I have the fundamental definitions. I found it odd that a person could be both, but, I do see that. Afterall few people can answer questions with yes and no, like I can.
As to whether intimacy of a routing would identify a persons type, my personal feeling is that the only separation, that holds water, is one between a game minder and a sportsman. Maybe, within that identification there's a correlation between intra and extra verts?
This year I met my first person who articulated that he preferred not seeing anyone else on the golf course. (separated corridors) So much so that he put his money where his mouth is, by joining a club whose course reflected that. He didn't seem intra-verted in the least.
