Age Avg M70 You — current You — optimal
Pulling all modifiable levers roughly doubles your chance of reaching 90 and triples your chance of reaching 95.

Top 3 Levers to Pull

Top 3 Active Threats

What might kill you, ranked

Probability-ranked death pathways given your current data. Click any row for the markers driving it and the interventions that move the needle.

Levers to pull, sorted by years gained

Estimated years of life recovered if you optimize each marker. Estimates are conservative — see Methodology.

Every marker, with consequences

Your numbers, what they cost or save you, and what to do about each.

What we don't know about you yet

Markers you haven't tested — sorted by years recoverable if you fill them in. Each card tells you what the test measures, why it matters for your profile, and how to get it.

Ask Doctor — checklist for your next visits

Specific things to ask each provider, with the medical rationale. Bring this list — every item is backed by your actual data or a peer-reviewed guideline. Sorted by visit.

The Method

How this works — and what you should be checking, and how often.

The three jobs

Track daily

The high-frequency signals — most matter for the next doctor visit.

Track weekly

Trends, not snapshots. Including the 30-second sit-to-stand strength test.

Track quarterly

Big-picture checks. Bring these to cardiology / PCP visits.

Second Opinions — the plaque-reversal landscape

Doctors and protocols that argue coronary plaque can be reversed. Three camps, with honest evidence assessment for your specific situation.

First — the honest truth about reversal

The doctors / protocols

Sorted by relevance to your profile (CAC 581, LAD stenosis, statin-treated).

Your medical history

The major diagnoses, treatments, and findings that shaped your current picture — in chronological order.

How these numbers are computed

Honest disclaimers and the sources behind every estimate.

The honest version. We do not predict your age at death. No one can. Instead, we start with the published population survival curve for a man your age in your state of residence. For you, that's California (CDC 2022 + CA Life Table 2020) — which has roughly 2-3% better survival than the US national average at each age band. Then we shift that curve by a combined hazard ratio (HR) built from your specific risk factors, drawn from peer-reviewed cohort studies. Your "current" curve uses your present markers; your "optimal" curve uses your markers with all modifiable risks fixed. Non-modifiable risks (age, family hx, accumulated CAC) remain.

This shows a range, not a date. You see the percent chance of reaching each age — not a single "you will die at X" number. The curves shift right or left; they never become a point.

Why location matters. State-level life expectancy varies by ~5 years across the US (Hawaii highest, Mississippi lowest). California is among the top quartile, mostly because of lower smoking rates, better healthcare access in urban areas, and lifestyle patterns. For a generic/blank version of this app, the user would be asked to specify their location so the baseline matches.
What's captured. Modifiable cardiovascular, metabolic, hormonal, and lifestyle markers with established mortality associations. Heavy weight on cardiovascular pathway because that's your dominant risk per CAC 581, LAD stenosis, family history, and lipids.

What's not captured. Accidents. Novel infections. Cancer surveillance gaps. Mental health. Cognitive trajectory. War-zone exposures. Black-swan events. These can change everything.

Confidence. Each marker carries a qualitative confidence level (high / moderate / low). High = directly studied in large RCTs or cohorts with consistent results. Moderate = consistent observational data, fewer RCTs. Low = mechanism-based or small studies.
