You mentioned the CAR-T program, which you're very heavily involved with. I believe from my previous meeting that techniques like that for treating a patient in the United States cost more than $450,000. You've developed innovative ways to bring that down to say, $100,000. It's still a lot of money. I'm just wondering, again, if you see an end point where it's far cheaper? This is exciting, as I say, life-changing, life-saving science for patients. How will patients be able to afford that? Are governments covering the cost of that when you're treating them?
I'll stop there because I'll just take up your time and I'd rather listen to you.
