A YouTube interview (Mar 12, 2025) with human biologist/longevity expert Gary Brecka and AI Mark. Brecka explains insights from large life‑insurance and annuity datasets showing modifiable risk factors (diet, mobility, supplementation, pharmaceuticals) strongly predict mortality. Key empirical claims in the chunk: heavier pharmaceutical use made life expectancy more predictable and shorter; insurers measure insulin, glucose and A1c; vitamin D3 deficiency (single-digit to low double-digit ng/mL) was common and associated with worse outcomes, while functional vitamin D ranges cited (50 ng/mL — 'nobody died'; 60–80 ng/mL — 'no deaths') correlated with far lower Covid mortality; corticosteroid initiation predicted joint replacement about 'six years and one day' later; social isolation and reduced mobility accelerate all‑cause mortality. Brecka frames effective biohacking as restoring exposures from nature (sunlight, air/oxygen, grounding/magnetism) and using hormetic stresses (cold plunge, breathwork); he endorses red light therapy (10–20 minutes/day) and PEMF as practical modalities.

Questions this video answers

Over 50 ng/mL (speaker also cited a functional range of 60–80 ng/mL with no recorded deaths).

Single-digit to low double-digit levels (example range given: ~7 to 25 ng/mL); he noted many labs use 30 ng/mL as a lower threshold and he considers 30 clinically deficient.

Less than 1%.

Six years and one day.

About 10 to 20 minutes per day (full-body red light therapy).
