 Well, I mean, what do you think? Because, you know, for example, like you think about something like lung cancer, and, you know, in the 60s and even in the 70s, smoking was so much more prevalent than it is now. Are there certain environmental factors that might be leading to some of these cancers? Is it just kind of a luck of the draw? Is there something else going on? I wish I could say it was the luck of the draw. Unfortunately, it's not.
