I used to work 2nd shift years ago...and I simply loved it.
I got to sleep later into the day but still have time to get things done before work, and shortly after getting to work almost everyone else left, and I got lots of work done when everyone was gone.
This was however back when most business were really open M-F 9-5 so, I guess now its alot different since you can get a great deal done more often, and so much can be done via the internet.
I didnt have a problem with human contact...I amuse myself quite well

Actually thats when I got to listen to all my own music and no one complained, bothered me, or joked so..that was nice.
