I think this is a top-notch discussion. I appreciate what you've contributed to this, and I appreciate the fact that there are multiple sides to every story.
In the time remaining, I'd like to just pick up, Maggie, on what you talked about as “windows of vulnerability”. I'm interested in knowing how you go about regulating that. For example, you have a welder who becomes pregnant and whose physician says she cannot continue to breathe in the toxic chemicals associated with welding. How do you practically regulate that, other than just removing the individual who is in that window from the environment? Or is that what you're talking about?
