This becomes important in the hiring process, as well. If the company offers health insurance benefits (and many do), they know the company's portion of the costs will go up when they hire someone overweight. And down the road, one of 2 things COULD happen: either the weight results in certain medical problems developing OR medical problems develop and the weight issue becomes a complication in treatment. An example of the first is that there seems to be a link between being overweight and developing diabetes. An example of the second is someone who requires surgery and has a lot of excess flesh which the surgeon has to deal with; the healing takes a LOT longer. I'm not saying it is right, just explaining HOW the discrimination can happen.

I can't think of how the height issue could happen though.

Being a short, pudgy (ahem! by quite a bit!) Sicilian female, I think I fit in to that legislation!
