I use to work at UUNET, I moved my office many times. The last few times I had six boxes, then eight. I didn't even unpack four boxes after my last move (and I was in that office for about two years), I did paw through them, so they were about half full. When I left I dragged out more then eight boxes (I think).
I have been at my new job for a while, maybe 8 months. I just packed up my office. I couldn't fill half a box. Ok, I took all my framed pictures home (so Office Movers can't break them), and one book (it's hard to replace). Still, I could fill a half box. Really.
Pretty pathetic for a pack rat like me.
Of corse I was at the last job for nine years...
