I located a directory of ergonomic consultant. If you visit this link you will be able to specify a location and find a consultant that will come to your home office. I plan to find someone to come to my office for an evaluation of my workstation. You can also call a local college or university to see if they have industrial hygienists that will be able to assist you. Although I have read material and made changes I am convinced that like Rhea and Cecelia have indicated it just makes sense if we are going to be bloggers.
But there are some things I can keep doing now and that is keep my posture good and get up stretch , walk around and dance when stressed.(smile) Hey, if I do that with each stressful moment I could lose weight.
