The researchers are comparing the time we spend walking against the time spent walking by a bunch of theme park actors they hired? How absurd.
No doubt there were people in history who moved about more than we do. There were also people who moved far less than we do, on account of being snowed in all winter, or chained to a Lowell sewing machine. And I think our diet is on average, better than theirs was. I don't claim to know the causes of the increase in heart disease, but I know specious pop sociology when I see it.
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.
