Sore muscles= Working hard

I associate sore muscles with hard work. Exercise, stress, strain, repetitive movements and motions.

So I know that I've been working hard when...

I have muscle spasms at the computer, from the computer (or at least the amount of time I've worked on the computer). Did you know that it takes much effort to hold my arm in a comfortable position when I'm dominantly using the mouse? It does. I never would have thought that. Maybe I AM a geek.

(Aaah! The pain of occasional acceptance!)
