Ergonomics is VERY important. I do certain things that work well for me. Typically I have my entire forearm resting on the table. Chair straight up and my monitor is raised w/ blocks so my head is in a neutral position. This makes all the difference in the world IMHO.
I've been using a optical mouse for a number of yrs. Any one using an old style track one has gotta be nutz. I use to have to clean the ball few times a day. I stopped picking up the mouse and banging it on the table as well ..... LOL: that surely didn't help my elbow or wrist I'm sure.
There are times I can't control what I have to do w/ my body.

A week ago, I had to tap around 30 holes that were 1.5" deep in metal and my back was KILLING me. Half of he holes I had my arms straight out so my neck & lower back were toast. Thank goodness I won't ever have to do that again until we replace a new machine!
Imagine how much worse it would be Scott if you didn't have the noggin to automated things!!! Let the machines do the work I say.
