Many of my friends work in traditions that tear their hair out over the focus on ‘posture’ and ergonomics. If you’ve ever worked in an office, you’ll have received advice about the best way to sit, or even that you should stand because otherwise you’re killing yourself. All nonsense really. Like my other posts on gravity say, we are floating on the surface of the Earth, there is no need to use any effort to sit or stand. But you have to know how to use gravity to float.
