I'm more than happy to answer you, Darren. Just let's do it in a formal way. 

For me, the important thing is that we look at efficiencies but also the costs. So, Cwm Taf can do hip replacements really cheaply compared to some of the other areas, so we've got to learn from those and some of those are about day care. So, certainly, that would avoid the problem in terms of the beds issue, which is the constraint on the system. So, lots to learn and that's what we'll be driving the system to do in the next few years.
