Ok, I don't know about anybody else, but I used to do data entry (and I spend quite a bit of time on my computer at home now) and I don't think I could walk and type at the same time. At least not and type accurately or with any speed.
So now they are willing to sacrifice speed and accuracy on work just to have thinner employees? Do they think what they supposedly will save on medical bills and insurance costs will more than cover lost productivity? And $4,000 for a workstation? Sounds a little spendy to me. When I worked for Young America Corp, we had about 400 people doing data entry in-house. I don't think they would have been willing to part with $1,600,000 for workstation/treadmills so we could exercise while we worked. And I think it would have been considered discrimination if they bought them for only the workers they considered fat and no one else.
I want to know how they know that everyone who sits at a desk at work all day long is also sitting in a car/bus/train on the way home, and then doing nothing at home but sitting on their ass in front of the television and/or computer. Shit, I forgot, it's only the fat people who do things like sit on their asses all day long, no matter where they are. And they are still counting on burning more calories = health. When are they going to get a clue?
