 You win. Well done. Thank you, Claudia. I'll let you win the next one. OK, we'll see. Thank you very much, Francesca. Thank you as well. Well, congratulations on your plunk skills. They were very impressive, James. But there was a really serious point here, and I know you've been having a look at the rest of this stand while I was talking to the scientists. And thinking of this idea of a blood test to predict who's likely to become most seriously ill, could you see how that could make a difference in a future pandemic in practice? How would it work in hospitals?
