Fascinating stuff. He's doing video diaries, poop reports...the works. Apparently all sorts of scientists are checking in as well on his progress during the experiment. As of today I believe he has 2 days left.
(I watched the diaries first and just listening to his accent I thought, "He's Canadian!" Yup. Thanks Canada for your willingness to be human guinea pigs. Or in this case...human monkeys. Huh.)
