Can these ultra-exclusive fitness clubs and residences help extend your life? They’d certainly like to try

But what if, by living there, people were also extending their lives? That’s the mission of the “longevity floor,” another amenity available to future residents of the Six Senses’ 251 apartments and “sky mansions.” This unique floor will include even more specialized offerings such as crystal sound healing, believed by its practitioners to reduce stress and improve sleep. Or residents can indulge in hyperbaric treatments, breathing in 100% oxygen in a pressurized chamber which has shown promising anti-aging results.

Celebrity personal trainer and gym designer Harley Pasternak is used to designing programs for high-profile celebrities including Kim Kardashian, Lady Gaga and Halle Berry. But he’s noticed a shift in the past few years, he told CNN over email, as he’s gained an “influx” of tech founder clients.

“All of them are definitely more interested in aging, in a way that I’ve never seen prior to five years ago,” he said. “All kinds of biohacking tricks like heat exposure, cold, exposure, certain supplements, training, foraging, and even certain medications.”

The dream of buying time

Experts generally agree that eating well, reducing stress, exercising and having positive social connections can all lead to a longer life, as can avoiding habits like smoking and drinking. And the wealthy already have the upper hand: Studies show those on the upper end of the socioeconomic scale not only live longer, they stay healthy for nearly a decade longer than others.

“The idea around it is that you’re not just purchasing a residence, you’re purchasing a lifestyle,” said Kevin Cavaco, director of marketing for Select Group, the building’s developer.

“You’re purchasing an opportunity to work on your true wealth — which is your longevity. You’re prolonging your time.”

Life extension may be a lofty — and dubious — pitch, but it’s a common theme among luxury fitness clubs, opulent new high rises and exclusive retreats. The trend coincides with new scientific studies and a parallel fixation in the tech world, butthe provable science behind these promises is often murky.
