 Well, it's going to be very interesting to see what happens next with this. Thank you so much, Andrew Green, for joining me from Berlin for Health Check from the BBC today. The producer is Margaret Cesar Hawkins, and our studio engineers today are Mike Mallon and Steve Greenwood. I'm Claudia Hammond, and next week on Health Check, I'll be with a live audience discussing the psychology of toxic positivity. It's that pressure from other people to be constantly positive and to suppress any negative feelings. But is it always good for you?
