Thank you very much. That was exactly where I was going to lead with the question anyway.
We've talked about life cycle. Dayna's talked about it. I don't know if you know who Philip Jessop is. He's a professor at Queen's who also talks about it. If we look at the life cycle of a chemical or an organism, we almost need to take a hybrid approach between risk assessment and hazards-based assessment in order to be both backward and forward looking. Could you expand on that. What are your thoughts on that?
