Good. Thank you very much.
To finish up this second round, are there any more questions from the opposition? No.
That's probably a good spot to end then, before we deal with our report from the steering committee.
If the committee will allow me, I have a couple of questions. On the issue of lessons learned, could you quantify how long it takes to implement change in routine, change in protocol, when something like that happens, when it feeds back up the chain? Does it happen quickly? Is it a matter of days or weeks? Does it have to be studied forever or can you make a pretty quick decision?
