The Honest Science of Living Longer: In Conversation With Eric Verdin, President and CEO of the Buck Institute

Eric Verdin runs the Buck Institute for Research on Aging, one of the world's leading centres dedicated to understanding why we age and how to extend the healthy years of life.

Given that vantage point, you might expect an elaborate protocol. What he actually does is nothing like what most people assume, and it says a lot about where the real evidence sits versus where the noise is.

We asked him where the evidence actually stops, whether there's an age when the basics quit working, and how a non-scientist can tell a real recommendation from an expensive guess. His answers cover the simplest way to start eating on a schedule, the one blood test worth asking your doctor for, and the single habit he'd want every reader to change starting Monday.

Short Hack Long Life

The Movement Floor (Walk More, Sit Less)

Verdin's number one prescription is deceptively simple: walk more, sit less. The data backs him up. A meta-analysis of 15 international cohorts found mortality risk drops steadily as daily steps climb, with the benefit plateauing around 6,000–8,000 steps for older adults and 8,000–10,000 for younger adults, meaning most of the return arrives well before you hit a "serious" step count.

Sitting less matters independently of that. In a randomized trial, breaking up prolonged sitting with a two-minute light walk every 20 minutes lowered post-meal glucose responses by 24% and insulin responses by 23% compared to sitting uninterrupted. The resistance piece Verdin adds on top isn't a big ask either: as little as 30–60 minutes of muscle-strengthening activity a week is linked to a 10–20% lower risk of all-cause mortality.

The Protocol:

🕐 When: Walk daily, accumulating steps throughout the day rather than in one block. Set a reminder to stand and move for two minutes every 30 minutes you're at a desk. Add two short resistance sessions a week, 20–30 minutes each.

🎯 Specificity: Aim for a floor of 5,000–7,000 steps a day before worrying about a higher target. Every half hour of sitting, get up for two minutes: refill water, take the stairs, pace during a call. For resistance training, six to eight compound movements per session (squats, rows, presses) at a weight that's challenging by the last few reps is enough.

🚫 Friction removal: Don't wait for a structured workout if that's the barrier, walking on calls, parking further away, and taking stairs all count toward the total. If you miss a day of walking or a lifting session, just resume the next day. No streak to protect, no catching up required.

📊 Tracking: Your phone's built-in step counter is enough, no wearable required. Track post-meal energy and afternoon focus for two weeks. Most people notice fewer energy crashes within 7–10 days, with measurable changes in resting heart rate and blood pressure over 6–8 weeks of consistent practice.

Why We Actually Train

Discussion: We asked the community one direct question: what's the single most important goal behind their exercise or gym habit?

The verdict: Answers ranged wider than expected. Several members prioritised staying functional over aesthetics, citing range of motion under load or simply "general function and wellbeing." Others framed training in biological terms, as a way to stay closer to autophagy and slow the compounding effects of ageing. And a few were refreshingly honest that competition, not longevity, is what actually gets them into the gym, with one member's long-running goal being to beat the men in her CrossFit class, calling it her top remedy for mental health alongside cold showers, as consistent a habit as brushing her teeth.

Consider this: The spread of answers is itself the finding. Whether your driver is mobility, biology or ego, consistency matters more than the reason you show up. If you want a marker that maps onto real functional capacity rather than just muscle, VO2 max is worth understanding.

Training Through a Heatwave

Discussion: With temperatures climbing, members asked how everyone else keeps training when it's 30°C outside.

The verdict: The community's answers split into two camps: adapt the timing, or adapt the environment. Several train early morning or in shaded, natural settings to avoid the worst of the heat, while others simply move indoors to an air-conditioned gym. One member's approach summed up the mood: close the laptop and jump in the sea, find AC, or aim a fan at yourself at close range.

Consider this: Heat adds a real physiological load on top of the workout itself, so hydration and electrolyte replacement matter more in summer training than most people account for. Worth checking your intake against a proper electrolyte source if you're training outdoors this week.

?

Discussion: A member floated the idea of people who build health apps as a hobby pooling their best features into a single open-source project.

The verdict: Open-source health tools have precedent — Apple Health export parsers, sleep-stage scripts, DIY CGM dashboards have long circulated in maker communities. Combining forces works best when the group agrees early on a shared data schema and a single maintainer.

Consider this: One combined tool beats a dozen bespoke ones in theory, but hobby open-source projects often stall once the original builder's motivation fades.

Community Health Stack

Erling Haaland

Erling Haaland is one of the world's most dominant footballers, fresh off leading Norway to a historic run to the World Cup 2026 semi-final this summer, where he finished the tournament with seven goals. Behind the goals sits a recovery and nutrition system built to let his body handle elite-level training and competition several times a week, treating recovery with the same seriousness as the training itself, from cold exposure to circadian light management.

Erling`s Health Routine

Morning

Haaland's day starts early, with sunlight exposure timed to anchor his circadian rhythm before anything else. He hydrates with filtered water and keeps the early hours low-stimulation, no screens or stimulants before his body has had a chance to wake up on its own.

Afternoon

Training centres on compound lifts with a power emphasis, targeting the core and legs, layered with functional work like sled pushes, balance drills, and unconventional movement patterns. Every session opens with dynamic mobility and activation work rather than static stretching, and closes with dedicated recovery: soft tissue work, stretching, and alternating cold and heat cycles.
