There’s always been plenty that money can buy: a designer wardrobe, a superyacht moored in Monaco, and a private jet on standby. The one thing it was never supposed to buy was more time. Yet that’s exactly what some of the world’s wealthiest individuals are now betting on, pouring billions into companies, technologies, and research designed to help people stay healthier, sharper, and more energetic for longer. The question is, how much of it will actually work?

Leading the charge is Altos Labs, one of the most heavily funded longevity ventures in the world, which, backed by billionaire investors including Jeff Bezos, is exploring cellular reprogramming—research aimed at restoring aged cells to a more youthful state. While the goal is not immortality, the ambition is undeniably bold: finding ways to slow, prevent, or even reverse aspects of age-related decline. Then there’s OpenAI founder Sam Altman, who has invested $180 million (Dhs661 million) into Retro Biosciences, a company aiming to extend healthy human lifespan by a decade, while PayPal co-founder Peter Thiel funds a range of biotech ventures, championing the idea that aging should be treated as a challenge to solve rather than an unavoidable fact of life. Not to mention Mark Zuckerberg and Priscilla Chan have committed billions through the Chan Zuckerberg Initiative to advancing disease research, prevention, and treatment.

While longevity may have become the latest buzzword in Silicon Valley, the growing fascination with aging well isn’t simply about billionaire vanity projects—for Assia Grazioli-Venier, co-founder and managing partner of Muse Capital, the growing interest in longevity is being fueled by genuine scientific breakthroughs as much as investor appetite. “We now have a real mechanistic understanding of aging at the cellular level that we didn’t have 10 years ago,” she says. “When you see aging as a collection of biological processes that can potentially be intervened in independently, it stops feeling inevitable and starts feeling like an engineering problem.”

As one of the few venture capital firms actively investing in women’s health, Muse has built its thesis around an area long overlooked by both medicine and investors—much of the existing science has historically been built on male data. “Just 2 per cent of healthcare venture capital goes to women’s health, yet women drive 80 per cent of healthcare decisions. That math doesn’t add up,” Grazioli-Venier explains. “Women have different hormonal timelines, different cardiovascular risk profiles, and different neurological aging patterns. Menopause alone is one of the most significant biological events in a human lifespan, yet it received remarkably little serious research attention until recently.” As more female-specific health data is collected, the next decade could transform our understanding of how women age and what interventions may have the greatest impact on long-term health.

For all the excitement surrounding longevity science, however, some experts believe the conversation can still lose sight of what really matters—being happy and healthy in the present day, too. Rather than chasing the latest trends, says Jason Leavy, founder of Prime Performance Labs and a specialist leadership coach who works with executives and founders across Dubai, London, and beyond. He advocates for focusing on daily habits, which, in turn, will benefit you in the long run. “Longevity becomes a natural output of looking after yourself in the present,” Leavy says. “My clients understand that what you do now will pay you back years down the line.” In his view, the strongest predictors of longevity remain remarkably simple: quality sleep, social connection, movement, and nutrition. “People get seduced by sexy new things, but all the high performers are the ones who consistently get the fundamentals right. That is 95 percent of the battle.”

One area he is particularly excited about, however, is brain health. While much of the attention is focused on the body, Leavy believes cognitive well-being deserves a far bigger role in the longevity conversation. “The brain is the CEO of the body, so what’s the point in maintaining your body if your brain is degenerating?” he says. With neurotechnology advancing at pace, from tools that enhance cognitive performance to treatments for anxiety and depression, he believes brain health is poised to become one of the most important frontiers in the wellness space. “Brain health is going to become mainstream, and I am very excited about that.”

Whether longevity ultimately becomes the next great medical breakthrough or simply another wellness obsession remains to be seen. What is clear, however, is that the conversation is no longer about cheating death—from billionaire-backed biotech labs to emerging women’s health startups, the focus is increasingly shifting towards helping people live better for longer. And while money may accelerate the science, the foundations of a longer, healthier life remain remarkably accessible: quality sleep, meaningful relationships, movement, purpose, and prevention. In the end, perhaps the real luxury isn’t adding years to our lives but ensuring the years we already have are lived as well as possible.
