 Well, maybe one other way, again, just another little piece of the puzzle here is trying to leverage what we know about cancers in older people. I do wonder about that because we spoke with Dr. Peter Campbell. He's a professor of cancer epidemiology at Albert Einstein College of Medicine. And of course, he too also acknowledged there's so much that we don't know about early onset cancers. But he also told us there could be lessons in cancer prevention that we learn from later onset cancers.
