Do you protect your body from desk abuse?

I was wondering if people are taking the time to make sure they are working in a safe environment? There's so much time we spend working at our desks, but in the real world, businesses are required to invest heavily in health and safety to protect their staff (and avoid lawsuits) from injury and subsequent claims. But who's gonna protect YOU as a self employed desk clinger? That's why this post is important in my opinion.

So, are you sitting comfortably? If so, are your wrists ever aching? How about your back?

Furthermore, what about your environment? Is it noisy, distracting or tranquil? What have you done recently to make sure you are working in a comfortable and productive environment?

Why do I care? Well, I guess someone ought to point out how much damage you can do to your physical body from sitting at a computer all day. (Eye strain, back problems, wrist problems, stress...)

Here's a suggestion:

Why not post a picture of your work office, so we can all see how you work? (I'll get one up too when my camera is charged)

P.S

If you've got a pimped out office, show it off! If you're working in a barn shed, then don't be afraid to confess...it could be killing you!
