 I grew up in South Africa. I grew up in Cape Town and I loved science. I was as a kid and very much into the science and mathematics and so on. And there was a competition in South Africa and the top group from that competition got to come to London sponsored by some of the local companies. And so it was this extraordinary mind-altering, eye-opening experience meeting kids from all over the world who had similar interests, similar backgrounds. Even though we came from such completely different cultures, we had this love of science that brought us together. And for me, it led to a bunch of new opportunities, new friendships. So it's fantastic to be back here and I'm keen to meet this year's generation.
