Until very recently being snowed in all winter meant constantly feeding a fire with wood or coal. Splitting wood or carrying coal is a lot more work than typing. Meanwhile, I don't think you can assert that sewing at the professional level is approximately as sedentary as keyboard work without data. The cloth doesn't cut itself. It doesn't load itself. You are constantly moving your hands and arms. Until the advent of electrical controls the machines had to be clutched and unclutched by hand, even if the actual power came from a central belt drive system. And so on.
