Deane. Again one thing that I do and Adrian does is, we constantly travel around the world to take a read on the economic environment. So you are going to get a view from our perspective, and I will share those thoughts in a moment. Again the newsprints, the newspapers are overwhelming amount of what I call [signaling the noise] of a potential economic slowdown for us to dismiss that out of hand, given that no one knows what the world is going to look like in six months to a year. I think we'll just be foolish. But let me talk about and I just concluded a world tour over the last from the end of December to January. And first thing you do, of course, you visit all the top managers, CEOs of your customers around the world, no evidence of any additional slow down other than the troubled market that we have already discussed, get all the feedbacks we received, business is okay, its good. Second thing; we constantly look at it, what is their behavior. In the capital market there's usually two behavior, the first one is, how hard is it to get PO signed, how many signatures are there to get a PO in a company. And sure enough, if you look at the markets that in fact are having some difficulty, there are more people having to sign off the time to get the PO approved is longer. We have not seen that in a lot of our growth markets that we've just described, a change in behavior on how acquisitions, capital investment are made. The second that we look for and I look for particularly, is when does the CEO send out a mandate that all capital spending stops on Monday, because again, that is always the danger in the future, if there is enough economic uncertainty or crisis, people would stop spending money, we have seen no evidence to date of any of that happening through our view of the world and this is my personal travel as well as the feedback that we have received from our thousands of direct sales people around the world. So again, cannot dismiss the rhetoric, particularly in the United States, in terms of concerns since we are acting prudently and the flipside of it is other than the well documented industries that are having some difficulty, we have not seen evidence or problems in any of the other submarket that we've described.
