This concept is not new - Donald Rumsfeld and others did it for years
This concept is not that new. A lot of people noticed a change and didn't like it when their jobs changed from active to sedentary.
I mentioned Donald Rumsfeld because when soldiers complained about having to stand for up to 4 hours. he replied that a young man and a soldier should be able to do that. Later ot was revealed that was not that outrageous be cause he had a standing desk and he was in his late 60s at the time.
