Mr. Chair, I have heard of that, and I understand why some people would say that. I have not reviewed any documentation or any evidence to support it, but that's not to say that it doesn't exist. I know that's an idea that's out there. It has some sense of reason to it, but I can't say that I've seen or read anything that would empirically support it.
