 Oh, wow. Well, thank you so much for coming along today, James Gallagher, and for playing so many games with me. That is it for now from the Royal Society Summer Science Exhibition. We'll put links to all the research we've talked about on the Health Check website. But if you're wondering about some of the other science on display here, then do have a listen to our sister show on the BBC World Service, Science in Action. Thanks to the producer, Dan Welsh. I'm Claudia Hammond.
