Top longevity competitors lowered their estimated biological age scores by a combined 62 years. Here's how they stay healthy.

Most longevity enthusiasts are trying to slow aging, but Adam Ficsor wants to outrun it.The software engineer and Bitcoin developer says humanity could eventually reach "longevity escape velocity," where advances in medicine extend healthy life faster than people age."I am talking about literally not dying," he told Business Insider for an episode of its video series "The Limit."To that end, he founded the Longevity World Cup, a competition that ranks who can wind back their biological clock the most.The inaugural event announced its first winners in January, awarding about $4,000 in Bitcoin-funded prize money.The scores were based on PhenoAge, a tool that estimates your biological age using your actual age (aka chronological age) and common blood markers like cholesterol, blood sugar, inflammation, and kidney function. Basically, it's a "blood test-based estimate of your risk of dying," Daniel Belsky, an associate professor of epidemiology at Columbia University's Robert N. Butler Columbia Aging Center, told Business Insider.Participants have about one year to achieve and submit their best results.

First-place finisher Michael Lustgarten, PhD, lowered his estimated PhenoAge by 22.1 years. Subtracting that from his chronological age of 53 by the end of the competition yielded an estimated biological age of 30.9.Researchers continue to debate how best to measure biological aging, and experts caution that scores like PhenoAge are statistical estimates rather than direct measurements of how fast someone is aging. Moreover, it's worth noting that large swings in biological age scores over short periods, such as weeks or months, can be difficult to interpret, said Belsky, who was not involved in the competition."To adjudicate these biohacking competitions is an invitation for people to hack the algorithm and generate what are ultimately non-informative results from them," he said.That said, Belsky added that PhenoAge can be useful for tracking broad improvements from healthier behaviors."If you're seeing changes in PhenoAge in response to improvements in healthy behaviors, better management of existing health conditions, or other lifestyle changes that improve the overall quality of your environment, then I would be more likely to trust what the algorithm is saying. That's what it's designed to do," Belsky said.With that in mind, Business Insider asked the top three winners of the Longevity World Cup to walk us through the habits and routines behind their results.3rd-place finisher Wen Zhuang focuses on fundamentals
