When you have a PhD place and are part way through it, to look at other studentships on offer and think "ooh, that looks interesting!"?
I still get emails from FindAPhD.com with new positions listed and sometimes glance at them.
I suppose I do the same thing when I see Postdoc or more senior positions advertised, then I remember that I have to knuckle down and get my own degree first.
I like to think that doing this is indicative of my broad interests, not that I am currently in the wrong place. I just wondered if anyone else does this?
