Amazing -- I beat Mark Zuckerberg at something. In 2011, the billionaire Facebook creator made a one-year pledge to consume meat only from animals he had killed or slaughtered himself. He posted his kills on his Facebook page, of course. But then he caved on his promise after only a few months. I'm sure Zuckerberg made his pledge in good faith. Turns out writing code and raking in millions is easy for him. Killing dinner is hard. I suspect it'd be hard for most of us.
