“Consider that we’ve designed most of our chairs to put us into the same exact position: knees bent to 90 degrees, hips at 90 degrees, and our arms out front for reading, steering, typing, and eating.
Then, with a nod to well-meaning ergonomics, we fine-tune our chairs to get our bodies into the position that hurts the least, so we can work harder and sit longer.
While it’s true that special chairs and cushions, ergonomic keyboards, and strategically placed monitors can sometimes help you keep carpal tunnel syndrome and back aches at bay, the issues go far deeper than that.
Over time, some muscles are casted in a shortened, chronically tight position, others are cast too long to be able to do their job.
Even our cardiovascular system can suffer from being in one basic position for long periods.
