Yes, if I may, just to follow up on that point. I think what Dr. Habash has raised is really an issue of the distinction between a decision based on science and a decision based on social, political, and personal considerations.
If I understand what he said for his own personal use of a cellphone, for example, he would reduce it, but he doesn't believe in changing the standards because there's not evidence to change them. That's where the science part of it is. The other part of it, as I said, is about involves social, political, and personal decisions--choice. And we live in a free country, so communities, I would say, should have the privilege to ban Wi-Fi if they want to, like Lakehead University did. It is a community and it has banned Wi-Fi. They have every right to, not based on science, but just based on their personal considerations.
