curious what does and doesn't constitute "nomad". e.g. I was based in Thailand and traveled around a lot for 2 years, which probably constitutes "nomad".

but then I moved to Spain and have been there pretty steady for 2 years. I fit a lot of "nomad" traits, except for the key definition: I haven't moved around.

There's a blurry line between "expat" and "nomad".
