here's what lara has to say on the subject. excuse me. it's not disgusting, it's science. mmm — i think it's both, actually. i look forward to finding out what's got lara spitting feathers later. but first, a story that will make your blood run cold. i'm in iceland, revisiting the freezers at decode genetics in reykjavik, where robots working in temperatures of —26 celsius look after the blood of iceland. over the last quarter of a century icelanders have donated nearly 2 million samples, all in the name of genetic research. if you want to know what —26 celsius feels like, it's very painful on the ears, you really don't feel like breathing very hard at all, and weirdly my nostril hairs are freezing up.
