Work standing up

I've heard of this before, but this article is interesting. Here is a clip... (who is going to give it a shot?)

WASHINGTON (Reuters) - Think work feels like a treadmill
now? Try a new desk designed at the Mayo Clinic.
They built what they called a "vertical workstation" -- a desk fitted over a standard treadmill. They persuaded 15 obese people to work at this treadmill-desk and measured how many calories they burned.
If an overweight office worker used this vertical workstation all day, every day for a year, he or she could lose up to 66 pounds (30 kg), the researchers report in the British Journal of Sports Medicine.
