There's an inventor, you don't just think of something in the bath, you go into the workshop and build prototypes, lots of them, and almost all of them are failures. We actually get quite excited about something fails, because that's how we learn. I mean the cyclones for my vet, Conclina, took over 5,000 prototypes. That's 5,000 failures before I'd cracked it. So our life is all about seeing problems that no one's tackled before, and coming up with radically new solutions. Thank you.
