 The bottom line truth up front is we don't know yet and we won't know for 10, 15 years and then we'll know what the effects are. And there's been plenty of drugs throughout the history of time that have come out. We thought they were safe and they turned out to be horrible. And then there's other drugs that have come out and we thought they were safe. And 50 years later, we can't find a single thing. We really don't have a bad thing to say about them. And it's like, well, this is kind of amazing that it does this thing and it doesn't really cost. But we don't know that.
