I can finally announce, with great delight, that I’ll be giving a fourteen minute talk about sanitation, shit and toilets at TED2013 in Long Beach, California, on February 28. The conference is called The Young, the Wise and the Undiscovered. I know I’m not the first adjective, the third is debatable so I hope I’m the middle. The line-up is amazing, terrifying. Peter Gabriel! A teenage nuclear scientist! Wow. Here is the programme. Here‘s the six minute talkshit talk I gave last year at TEDLondon.
