In Beijing yesterday, Bill Gates spoke today at a conference with a fantastic name: the Reinvented Toilet Expo. The Microsoft founder took with him to the lectern a sealed jar containing human faeces, according to BBC News. Gates reportedly pointed to the poop jar and said that it could contain “as many as 200 trillion rotavirus…20 billion Shigella bacteria, and 100,000 parasitic worm eggs.”
