On: Who Wrote at Standing Desks? Kierkegaard, Dickens and Ernest Hemingway Too

I think that's just like starting to run by doing 5kms the first two days, you're going to be injured. It needs to be built up at first.

On the other hand, my own experience with doing one 25-minute Pomodoro standing per day is that it isn't enough, too easy to stop doing it.
