Chris Rowan is moving to the US, following his 3rd postdoc. So congrats to Chris! He's moving to his third continent for work.
It would be really neat to live and work in different countries, in theory. But I don't really have the constitution for it, especially right now. I'm working a couple hundred miles from my home base, working in a job that was supposed to be a temporary step but is becoming permanent thanks to an utterly horrendous economy. I don't have any connections here, other than this job and my sweetie, and it's really, really lonely.
Maybe if I had a job I really enjoyed, using the science I got an advanced degree in, things would be different. But I can't imagine living any further from my support network than I already am.
