IF YOU’RE DOING A PUZZLE, YOU ARE DISCONNECTED AND ENGAGED IN A TASK THAT’S IMMERSIVE

of jigsaws in particular. “If you’re doing a puzzle, you are, by definition, disconnected and engaged in a task that’s immersive, away from the interruptions and stresses of day-to-day life,” she says. “And that, of course, is good for your brain.”

Vandermorris believes that doing puzzles with others boasts even more health benefits than doing them on your own, adding that it provides a rare opportunity for intergenerational engagement. “Get the teenagers off their smartphones and working on a puzzle with Grandma, and suddenly you’ve got a really nice family interaction that seems to be harder and harder to come by these days.”

Interaction was certainly hard to come by for Jack Brait. The 23 year old has aut ism and first took to puzzles as a kid because they “gave him a break from the demands of socialising,” says his mother, Michele Brait, who soon realised her son had a remarkable ability. “He could complete a 1000-piece puzzle in one sitting,” she recalls.

As Jack grew, so did his puzzling talent – and its benefits. In 2014, while still in high school, he completed a 32,256-piece puzzle (then the largest in the world) and was inducted into the Ravensburger World’s Largest Puzzle Hall of Fame. Three years later, he tackled another behemoth: 40,320 pieces. Last year, he finished a 52,110-piecer.

Jack completed these puzzles by himself, but what used to be an escape from socialising now facilitates it. His oversize works attract attention, and he is more than willing to share the spotlight. “When I completed my first giant puzzle, I invited friends and family,” he says. “I enjoy doing them around other people.”

But the best is when one of his puzzles is put on public display, as Jack likes to donate his handiwork. That, he says, makes him feel “unbelievable, proud, and happy.”
