Branson is well-known for his adventurous side, and you've likely seen many a photo of the Virgin Group founder kitesurfing and hanging out on the high seas. But perhaps his favorite hobby is far more of a mental activity.
"I think chess may just be the best game in the world," he writes on Virgin's blog. "It combines the greatest aspects of many different sports — tactics, planning, bravery and risk-taking — plus you can have a cup of tea and often a stimulating conversation while you play!"
Branson says he's likely played thousands of games in his lifetime, and he tells The Telegraph afternoons on Necker Island are always spent on the beach, oftentimes playing chess with his kids.
Jack Dorsey hikes
In 2011, when Dorsey was running Twitter and Square full-time for the first time, the cofounder told the audience at Techonomy 2011 that, to get it all done, he gave each day a theme. This allowed him to quickly recall and refocus on the day's task once distractions were out of the way.
Dorsey said he would dedicate his Saturdays to hiking.
In fact, tons of celebrities, especially actors who have plenty of time to kill on set between takes, love to spend their free time knitting. The list includes Julia Roberts, Ryan Gosling, and Christina Hendricks.
As Business Insider previously reported, the actor and filmmaker has been collecting vintage typewriters since 1978, and he uses one every day because he loves the sound, feeling, and permanence that comes with typing on one.
"Everything you type on a typewriter sounds grand, the words forming in mini-explosions of SHOOK SHOOK SHOOK. A thank-you note resonates with the same heft as a literary masterpiece," he writes for The New York Times.

Steve Wozniak plays polo ... on a Segway
Apparently Segway polo is a thing, and the Apple cofounder is the namesake of one of the sport's major world tournaments, Woz Challenge Cup, the World Cup of segway polo. The game is played in four quarters, and five players on each team try to get a rubber ball past the opponent's goalie.
The "Project Runway" cohost and mentor told The New York Times that he spends every Sunday at the Metropolitan Museum — "I stay there basically until the museum is about to close."
He dons a suit — "I want to prepare myself properly" — and walks through Central Park to get there.
"I'm a huge lover of art," he explained. "I go to the Greek and Roman galleries first. I'll choose different objects to fixate upon. A trip to the Met can be very emotional. There are paintings there that just lift me off the ground. I feel buoyant."
He then heads to the Balcony Lounge for a glass or two of wine and tea sandwiches and pulls out his iPad to research what he's just seen. "I have become insatiable on the topic of ancient Rome."
Jolie tells W Magazine that her mom introduced her to daggers when she was a kid, and that she has passed this hobby on to her son, Maddox. She says the knife blades she gives him are dulled so he can't hurt himself, and that their dagger purchases are always "accompanied by discussions about violence."
In another interview with Conan O'Brien, Jolie shows off her skills with a butterfly knife and explains that her fascination with weapons comes from the history behind them: "There's just something beautiful about them."
