I was talking about health and prevented lung cancer deaths, not the cost of remediation. I'm not sure if we're talking about the same thing. We just did a rough estimate. We looked at the cost of lung cancer deaths and the number of lung cancer deaths that is expected if you're above 200. That's how we came up with that calculation, so if you lower the guideline to 100, you can probably expect that number to at least double.
