In an attempt to figure out whether Mark Zuckerberg is actually sticking to his resolution to run a mile daily, a very observant Observer reporter took the time to closely examine pictures of the Facebook CEO running. Her conclusion: Zuck is totally faking it.
I think this theory has merit. The most damning evidence: The recent photo of Zuck running through Beijing—on a day when air pollution was dangerously high—with a wide grin on his face. Nobody looks that happy choking on smog.
