Zuckerberg, the 27-year-old founder and CEO of Facebook, has taken on a new hobby, according to Fortune, which reported that Zuckerberg updated his status on his personal Facebook page: "I just killed a pig and a goat."
Zuckerberg chooses a new challenge each year that helps him get away from all things Facebook.
In an email to Fortune, Zuckerberg said he chooses a "personal challenge -- something to learn about the world, expand my interests and teach myself greater discipline."
In 2009, Zuckerberg wore a tie every day. Last year, he spent an hour each day learning Chinese."
