In a Nutshell

Human Longevity's screening of 10,000+ "healthy" people revealed ~2% had brain aneurysms, ~2% had undetected tumors, and many had severe coronary artery disease (calcium scores up to 1,500 with 80%+ blockages). Genome accounts for 40-55% of lifespan and heart attack risk, enabling polygenic risk scores to identify high-risk individuals in their 40s who can reduce risk back to normal through LDL, Lp(a), and CRP reduction. Current population-based medicine fails to detect these conditions because 2% prevalence isn't cost-effective at scale, despite 100% risk for affected individuals.

Human Longevity has screened over 10,000 people who declared themselves as healthy. The landmark publication in Proceedings of the National Academy of Sciences from 2000 summarized initial findings from 1,200 clients and these findings continue to hold true after screening more than 10,000 individuals.

Approximately 1.7-2% of people screened have a brain aneurysm. This represents a significantly higher prevalence than commonly expected. For example, statistically speaking, approximately 1.7-2 people out of every 100 on the street would have an aneurysm. This condition represents a ticking time bomb if left undiagnosed, as evidenced by the case of a dinner companion whose cousin died of a brain aneurysm in their 30s.

Nearly 2% of people screened have a small tumor growing in their body. Additionally, certain individuals have coronary artery calcium scores as high as 1,500, and subsequent CTA imaging reveals arteries that are already 80% blocked. One documented case involved a person with 80%+ arterial blockage who was warned to see a cardiologist immediately. The individual experienced a heart attack between the exam and their scheduled appointment but survived because they were prepared and called 911.

Screening reveals carriers of genes including BRCA1, BRCA2, and Lynch syndrome genes, representing various genetic predispositions. The data shows that for heart attack risk, approximately 10% of any given group of 100 people are at high risk for coronary artery disease.
