Do the news articles about Health insurers using the question "do you have any past health issues" and only looking into your past if something expensive comes up. I read about this woman who had something minor, such as ear infections as a child you, and forgot to put it on the intake form. So years later when she got cancer the Insurer dugg into her past and found the minor issue that she forgot to put on the intake form. This was such a big deal a Senator grilled the insurance company about it but they responded with "we are just doing what we our stock holders hold us to" or something like that. I wish I could find the article that talked about this.
