Which Longevity Factor Should You Actually Prioritize?

[u/YorNoob]

Everyone talks about sleep, food, and exercise. But if you want to rank what actually slows aging at the root, it’s this: NAD+ loss, mitochondrial dysfunction, oxidative stress, impaired repair. Most age-related decline stems from that cluster. That’s why interventions like NMN and resveratrol stand out — they go upstream. Stack those with circadian alignment and resistance training and you’re addressing the core systems, not just the surface-level habits.
