In Douglas Coupland's Generation X: Tales for an Accelerated Culture, he describes the cubicles in the one character's office as "veal-fattening pens." However, some folks no longer aspire to be veal. Instead, they are getting on gerbils wheels.
The Cincinnati Enquirer has the story of some lawyers who have stopped virtually and started literally spinning their wheels by using treadmills as their desk. Note that one of the attorneys mentioned spends up to four hours a day on the treadmill desk. That must be quite a glow by the end of the day. I assume that Mr. Torvik will get one of these desks right way as it will allow him more time to make it all work.
I'd like to be able to say I understand this impulse. But I don't. I spent most of my twenties and thirties at jobs that required standing all day. By the end of the day, my feet would really hurt. This was especially true on the days I worked a double shift. When people ask what I like about being a lawyer, one thing I mention is that I get to work sitting down. It is not the first thing I mention but it is in the top five.
