LOL, I've been working the graveyard shift for the last couple of years now. I try to keep up on astonomical stuff since I'm up anyway.
I'm actually going to be changing my hours for the summer so I'll be working a day shift. It'll be wierd pretending to be a normal person again.
I hear you there! Night shifts are great for astronomical interests. I watched the International Space Station cross the sky last year when it came close to earth. I wen't up to the roof of the hospital 20 stories high LOL and watched it. It was pretty cool.
