We had a fellow come into the office to conduct a workshop in ergonomics. It sparked more interesting thoughts than you might think. For example, if slouching is so bad for you, why does it feel so good? Further, does it add more fodder to the growing pile of data that anything one might enjoy: bacon, sausage, beer and buffalo wings are all some form of cosmic bait and switch?
He also mentioned that a way to avoid injuries related to being a knowledge worker type is to stop working every 20 minutes, get up walk around, do some stretches, etc. So I guess if you hire a lot of people with Attention Deficit Disorder you’ll save a boatload of money on works comp insurance.
