On a recent airplane trip, the airline magazine contained many ads for various desk configurations: stand, sit, cycle! All aimed at a healthier life for people in cubicles or home offices. Great fad--great for the makers of these complicated movable surfaces.

For ten years prior to my retirement, I sat at my desk on an inflatable exercise ball, in hopes that the movement, shifts in balance, etc. would help with my weight management. Meh. Luckily I only fell backwards once and nobody knew it. The OSHA folks were very much against this nonsense in the office.
