Let me start and then I've got to tell you. So, obviously, for me, I've been in the business long time, 39 years, obviously, the entire managed care was absolutely missed in terms of the benefits of managed care, in the pricing, what happened with it, I think you've got pundits on the side of what lower unemployment does to comp versus what higher unemployment does to comp, I don't see those necessarily fully panning out in the numbers either relative to the quality of work or people not wanting to go out on comp in different environments. So I can just tell you this, the rating agencies, the rating bureaus, excuse me, it's more attractive the correct term, are not really looking at forecasted trends, what could happen, what could marijuana do, for instance, in the workplace, what could that do to frequencies, what could be a recreational - so in that case, recreational marijuana I'm referring to. They're not really particularly insightful at looking out and saying what may or may not happen, what may happen to trends. Like John told you look, it's not going to continue to - severity can't continue to decline, we can't keep giving up in an array - in line where medical is the driver and whether it's Rx, hospital services or doctor services. Those are all traditionally under a lot more inflationary pressure than any other part of what we offer as part of the cost of goods sold.
