Hi Charina,
Great article. I learned this secret from my Grandfather when I was young and further practiced it in my year abroad in China. Now, I do this all the time at my startup, energy-efficiency software company.
I also know that it's been encouraged at some of the larger, well-known software companies as well. This probably won't be allowed in the manufacturing or labor type industries, but for software, and "knowledge" industries I think this will become a regular part of the work day.
