My brain is fried

I was working in the sun all day today and didn't have enough water. My brain is totally fried.

I'm using two computers with one mouse/keyboard (by way of synergy) - and I keep getting confused over which computer is performing a particular task (chatting, forum reading/posting, playing music, etc). I keep moving to the wrong screen for a thing.

I'm also trying to switch firefox tabs on the window manager's task bar

- I need to get some water, food, and sleep.
