Sure Julian. So maybe a couple of things I'll say too as well. So when you think about the PST, think about it as -- even when you exclude the life science business, PST on 10 out of the 11 past quarters has been positive on organic orders and actually all organic revenue. So that tells you kind of the good strength of the rest of the PST segment. I mean clearly, the life science, which is roughly about a quarter of the PST has been on this kind of situation with biopharma, but also oxygen concentration. And the life science business has been pretty negative organic order growth momentum for probably the past six quarters. So it's been now a little while, while the non-life sciences has been positive. So, yes, I mean, we're experiencing these challenges that others have indicated on our life sciences. I mean, I think the way we think about it is that for us, biopharma, yes, we have some exposure. But it's not the biggest piece of our life science end market exposure within the PST. The biggest exposure for us is really oxygen concentration. And the oxygen concentration, when you think about it, really a great acceleration during the COVID days, and is the one that we saw building into negative, more pronounced earlier than even the biopharma. So it was almost like a leading indicator for us. So, as we kind of go here into the fourth quarter and maybe in the first half of next year, we see that more so next year maybe an uptick, not in a V-shape, but continue doing better from an oxygen concentration side of the business. So, we continue to think that PST, as even you saw on that segment slide, I mean, PST CAGR growth organically, revenue and orders momentum continues to be a segment that we'll see that mid-single-digit plus over the cycle and over time. I mean, it's with great characteristics on continuing to improve in that. So Again, I don't think it's going to be a V-shape, but even if it's a V-shape, it's not one that -- again, we don't have that big exposure into biopharma.
