Science:
Of hundreds of biomarkers in modern medicine, four have the strongest predictive power for all-cause mortality and health span: VO2 max, grip strength, fasting insulin, and c reactive protein. Most people have never had all four tested.
Action:
Request fasting insulin and CRP on your next blood panel — both are omitted from standard panels.
Measure grip strength with a handheld dynamometer — it predicts mortality more accurately than blood pressure.
Estimate VO2 max: 15 x (max heart rate / resting heart rate)
Establish your baseline for all four this week — you cannot optimize what you have not measured.
Dose and Frequency:
Test annually. Track trends over time — the direction of change matters as much as absolute numbers.
From the Neurologist:
These four biomarkers reflect four systems the brain depends on entirely: cardiovascular oxygen delivery, musculoskeletal reserve, metabolic signaling, and systemic inflammtion. Neurons consume 20% of total body oxygen at rest — any impairment in these systems directly accelerates cognitive aging.
Call to Action:
Before your next appointment, write down these four tests and request them from your doctor. Most physicians will order them — they simply are not on the standard checklist.
