This raises an interesting question: is weight-related information considered private? On first blush, such an idea makes no sense – anyone can look at you and judge your weight, the same way that anyone can judge your eye color — but to me, the difference between judging weight from 3 feet away and pulling out the calipers to do a body-mass-index (BMI) measurement is a difference that crosses a critical line.
Would you consider your annual income to be a private matter? Me too. You may be able to take a guess based on the car I drive or the house I live in — you may even conclude that I’m well off. I certainly cannot prevent you from deciding I make a good living. I can, however, refuse to provide details, thank you very much. Those details, as guessable as they might be, constitute my private business. Public disclosure of such details would be uncomfortable, embarrassing, and invasive.
By the same token, my body-mass-index is also my private business. It constitutes something only I need to know. It is a piece of data strongly connected to my dignity. The idea that this information has to hang out for the consideration & judgement of the hostess at TGI Fridays is frankly repulsive to me. There seems to be an idea that this is no different than denying alcohol to a drunk person; the difference being that government restrictions on public intoxication are not expected to cure alcoholism. Do these lawmakers really think that restrictions on public eating will cure obesity?
