Every evening in Davos scholars, celebs and politicos swarmed around our booth in a hallway of the main conference hotel, where 23andMe offered WEF attendees a free look at their DNA. All they had to do was spit in a tube (and sign our consent form), then wait a few weeks for their information. Hundreds of people took us up on the offer — including a few you may recognize.
After the jump, a few more photos of famous people spitting (or about to spit):
