The really good opportunity for you here is to talk about how we're going to responsibly lay in these instruments. These are based on science. Frankly, you would find reasons to be very proud of the rigour our scientists bring to their exercise. We actually spend a lot of time talking to them, because we need to know what the data gaps are for them, what they need to know, so they build confidence in a drug before it goes on. There's a lot that goes on in that.
I think you would have reason to feel very good about that rigour. We don't want to displace that; that's not the idea. We want to bring really good science, and that's hard to do with rules that are 40 years old and straining to keep up with the modern science, actually.
