VERY OT, as usual, but I was interested in Ted S's remark about job change and the "bouncing upward" that often happens when one is forced out of one's (apparently) secure position.

I've had a similar "career" (my career has been more like the verb "career" than the noun...) and come to the conclusion that for guys like me a kick in the butt from the economy (substitute: wife, fate, lousy boss, merger, acquisition, plant closure, divorce, etc.)is usually a good thing, however stressful in the short term.

Most of the people I know who got the old time "job security" (such as academic tenure) have been miserable for years. I haven't had time to think about it much. (Be careful what you wish for?...).
