 That's it for this episode of BBC Trending with me, Mike Wendling. My thanks to Cheyenne Saderizadeh, to our colleagues Olga Robinson and Paul Myers. The producer was Olivia Lang and Flora Carmichael was our editor. If you want to get in touch, you can do so by emailing me. My email is michael.wendling, that's W-E-N-D-L-I-N-G, at bbc.co.uk. And we'll be back at the same time next week.
