A street in the Cuban capital, Havana, is home to 12 sets of twins, ranging from toddlers to senior citizens. Some say it could be something in the water. Others point to a tree with mystical significance for locals. And maybe it's just chance.

In 2002 photographer Corey Arnold left behind a poor economy in San Francisco and headed up to Alaska to try his luck at his longtime passion of fishing. Arnold, who had worked summers during college on a salmon boat in Alaska, signed onto the f/v Rollo, a crabbing boat that fishes in the dangerous Bering Sea. While working long, strenuous hours on the Rollo, Arnold often stole away with the captain’s permission to grab his camera and photograph the crew and the ship. Arnold eventually put together “Fish Work: Bering Sea”, a documentation of his seven adventurous and dicey crab seasons aboard the Rollo. (Photo by Corey Arnold)

“A cuddle party or cuddle puddle is an event designed with the intention of allowing people to experience non-sexual group physical intimacy through cuddling. Cuddle parties are described by organizers as “workshop/social-events” that gives adults an opportunity to “give and receive welcomed affectionate touch in a no-expectation, friendly setting, according to your needs, desires, interests, and boundaries”. Cuddle parties are described as non-sexual events but kissing may occur at some parties”. – Wikipedia

Started by Reid Mihalko and Marcia Baczynski, cuddle parties are events for adults to get together and explore affectionate touch and communication without it becoming sexualized. At the parties, strangers spend time introducing themselves and setting boundaries before lying down to cuddle. (Photo by Spencer Platt/Getty Images)
