21 years.

That's yours to gain.

The gap between optimal health and doing nothing has been measured — across 61 lifestyle factors, in landmark peer-reviewed studies. It comes to 21 years of life. The Longevity Lab exists to help you close that gap, one evidence-based intervention at a time.

The Science

Where 21 years comes from.

We translated hazard ratios from landmark epidemiological studies into years of modifiable life — anchoring each category to the best composite evidence available. These aren't estimates pulled from a single paper. They're calibrated against Li et al., GBD 2019, and Ding et al.

5.5 yrs
Exposures
Tobacco, alcohol, benzodiazepines, sleep aids, and medication overuse. The single largest modifiable domain.
4.0 yrs
Physical Activity
Steps, aerobic activity, strength training, sitting time, and sauna — anchored to Ding et al. 2016 (Lancet).
3.5 yrs
Nutrition
20 dietary factors — from legumes and olive oil to sodium, processed meat, and sugar-sweetened beverages.
2.5 yrs
Biometrics
BMI, blood pressure, grip strength, gait speed, VO₂ max, balance — measurable fitness markers tied directly to mortality.
2.0 yrs
Mental Health
Depression, social isolation, loneliness, marital status, and sense of purpose — all with meaningful all-cause mortality data.
1.5 yrs
Sleep
Duration and REM quality. Anchored conservatively given overlap with mental health and physical activity.
1.5 yrs
Labs & Imaging
HbA1c, insulin resistance, lipids, apoB, CRP, RDW, uric acid, vitamin D, and CAC score.
0.5 yrs
Supplements
Currently limited to glucosamine (HR 0.85). Modest but real. Kept conservative without RCT confirmation.

Category budgets reflect composite epidemiological estimates, not the sum of independent hazard ratios — which would overestimate due to shared risk pathways.

Dr. Nicholas Cohen, MD

Medicine practiced the way it should be.

Board-certified in Family Medicine and Lifestyle Medicine, Nicholas Cohen, MD trained at NYU School of Medicine and Case Western Reserve University. Before medicine, he served as a physician with the U.S. Army Rangers at the 82nd Airborne Division — where he learned what it means to operate systematically under pressure.

After 15 years in clinical practice — including time at One Medical — he founded The Longevity Lab to focus entirely on the work that matters most: catching problems early, building the habits that compound over decades, and giving each person the time and attention that a 15-minute visit never allows.

Outside the practice, you'll find him in the mountains — skiing, climbing, and field-testing his own protocols.

Common Questions

Good questions deserve honest answers.

The Longevity Lab is designed to work alongside your existing primary care — not replace it. Think of it as a specialized layer of proactive, preventive medicine that most standard practices simply don't have the time to offer. The focus here is the optimization and longevity work that falls outside a typical 15-minute annual visit.
No. The Longevity Lab operates outside the insurance model by design. Working directly with patients means the time and attention each person needs — not what an insurance schedule allows. Superbills are available upon request for out-of-network reimbursement.
All consultations are conducted via secure video call, so you can participate from anywhere. However, New York State licensure applies to any formal clinical work — so patients need to be NY-based for the physician-patient relationship.
You complete a detailed intake covering lifestyle, medical history, family history, and current labs — including a 61-factor longevity assessment. That data is reviewed in full before the Deep Dive, which is a dedicated 60-minute session to map your risks, set targets, and build a personalized protocol. You leave with a written plan, not a pamphlet.
No. The ongoing partnership has no long-term contracts. You continue because you're getting results and value the relationship — not because you're locked in. Cancel at any time with no penalties.
A board-certified physician with 15+ years of clinical experience can interpret bloodwork, diagnose conditions, understand drug interactions, and make clinical recommendations. That's a different category entirely. The Longevity Lab combines the depth of medical training with the kind of ongoing relationship that most clinical settings don't have the structure to support.
