of lifespan extension
Synthesizing the strongest evidence for longevity — from population epidemiology to cutting-edge experimental interventions.

lifespan range
heritability
Key finding: Cardiovascular risk control, muscle mass preservation, and VO₂max are the three strongest predictors of longevity — accounting for up to 20 years of life expectancy difference between individuals.
Hierarchy of evidence
Strong evidence · proven interventions
↓ Blood pressure · LDL/ApoB · insulin resistance · visceral fat
- Lower BP (systolic <120) reduces CVD by 40%
- LDL / ApoB control delays atherosclerosis onset
- Visceral fat is the primary metabolic aging driver
Strength training · lean mass · sarcopenia prevention
- After 30, muscle loss accelerates — sarcopenia risk rises
- Low muscle mass correlates with ↑ all-cause mortality
- Strength training is the strongest survival predictor in cohorts
Aerobic capacity as the primary lifespan biomarker
- Highest single predictor of all-cause mortality
- Steep mortality drop with even modest VO₂max improvements
- Small gains in sedentary individuals yield outsized effects
Low fasting insulin · stable glucose · low triglycerides
- Metabolic dysfunction drives oxidative stress cascade
- Mitochondrial damage accumulates with poor glucose control
- Chronic low-grade inflammation is the aging accelerant
Experimental · promising (human proof limited)
Senolytics
Remove senescent "zombie" cells to reduce tissue inflammation
mTOR Inhibition
Rapamycin and mTORC1 inhibitors targeting cellular aging pathways
NAD+ Boosters
NMN · NR · Mitochondrial biogenesis support
Epigenetic Reprogramming
Partial Yamanaka factor expression to reverse cellular age
Gene Editing
CRISPR targeting aging-related gene variants for repair
Epigenetic Clocks
Biological age measurement tools entering clinical validation

| Muscle mass preservation | 30–40% risk reduction | ★★★★★ | Strong cohort data (NHANES, Health ABC) |
| VO₂max fitness | 13% per 3.5 ml/kg/min | ★★★★★ | Cooper Center, HUNT study |
| Metabolic control | 2–3× mortality risk | ★★★★☆ | Strong mechanistic evidence |
| Senolytics | Unknown in humans | ★★☆☆☆ | Promising animal data; Phase 1/2 underway |
| mTOR inhibition | 25% lifespan in mice | ★★★☆☆ | Human trials ongoing (ARPA-H) |

Key takeaways
Cardiovascular
The largest population-level impact. Control BP, LDL, ApoB, and visceral fat.
Muscle Mass
Strength training saves lives — 30–40% all-cause mortality risk reduction.
VO₂max
The strongest single fitness predictor of longevity. Even modest improvements matter.
Metabolic Health
Keep oxidative stress, inflammation, and mitochondrial dysfunction in check.
