When you are sat at your PC working, do you have any habits (good or bad) that you do regularly when working?

I have several, the main one being that i boot both of my PC's up and use my laptop for actual 'work' and the desktop for games and image related stuff, no idea why but i just dont do stuff other than work related items on my laptop LOL

I guess it comes from always having had a laptop around me, even when ive got a perfectly good desktop sitting less than a foot away from me :wacko:

So what working habits do you have when you are sat at your computer?
