Since I live in Washington DC and work for a company in San Francisco, I can't exactly go into the office every day. Instead, I work from home. Yet even there I am a little different from the rest. I don't have a sitting desk with a chair – I stand to work.
I do have to say that I love my standing desk. I no longer have back or shoulder pain that plagued me when I sat for 10 hours a day, and contrary to what you might think, I'm not tired at all in the evening. I feel refreshed actually, because I've been moving around all day and not tied to a chair. In fact, my only real worry is how I can stay standing for the rest of my career!
