Thank you very much.
It has been extremely interesting, gentlemen, and I thank you for coming to our committee.
I think it's challenging for those of us who are not scientists, because a lot of the terminology that's used is hard to grasp. There have been suggestions that there are gaps in our knowledge and that there's inadequate information. Of course, that's sort of the continual state of science, isn't it? We never know as much.... If we knew everything, we could just put down our tools and stop studying. Correct?
Does that surprise you, that there are gaps in our knowledge?
