Yeah, I think, that's focused. I mean, pharmaceutical sales at the end point retail pharmacy sales are kind of where they're looking to disrupt. And so that's different than research driven manufacturers. And I've always thought that current system is pretty inefficient, when you have PBMs, the pharmacy benefit managers between the manufacturers and the ultimate users and so forth. So I think, to me, I think, it's going to rationalize the system. But I don't think that's weighed so much on drug stocks, I think, each one has been somewhat individual. Celgene made a pretty major change in their 2020 guidance on overall revenues, Merck had an EU issue with Keytruda, their new cancer drug. I mean, each one is kind of the explainable. As I said, Vertex has kind of knocked the ball out of the park this year. A recent M&A transaction Kite, was purchased by Gilead for almost $12 billion, and just got approval on the second cancer immunotherapy. So I think, we're pretty comfortable, the index, at least, on the biotech side is up, it was at almost 19% year-to-date, which is certainly outpaced many of the other industries. So I think, we feel pretty good, I think, the regulatory side is super positive with Scott Gottlieb. I think, the tenor [ph] in Washington is constructive, and I think, there is a positive business climate behind it. And if the - whatever shape the current tax bill takes place and we're able to - the industry is able to repatriate both at the biotech and pharma level, hundreds of billons of dollars, maybe between $100 billion and $200 billion or more from overseas cash that's going to be a net positive for the industry. So I'm pretty bullish.
