The Minerals in Your Water and Why They Matter
Magnesium, calcium, and trace minerals — the longevity connection most filtration systems get wrong.

Longevity
Evidence-based habits that extend healthspan, not just lifespan.
Living longer is easy; living better for longer is the real game. Longevity science has converged on a handful of high-leverage levers: muscle mass, cardiovascular fitness, metabolic health, sleep, and meaningful social connection. Optimize these, and most chronic disease becomes statistically rare.

What actually moves the needle
01
Build (and keep) muscle
Sarcopenia is the silent killer of independence. Lift progressively heavy weights 2–3× per week from your 30s onward. Muscle is metabolic insurance, fall prevention, and brain protection in one.
02
Train your VO₂ max
Zone 2 cardio 3–4 hours per week builds the mitochondrial base. Add one weekly high-intensity session (4×4 intervals) to push the ceiling. VO₂ max predicts longevity better than smoking status.
03
Defend metabolic health
Track fasting insulin, ApoB, and hs-CRP — not just cholesterol. Most heart disease and dementia begin as insulin resistance decades before diagnosis. Walk after meals, prioritize protein, limit refined carbs.
04
Invest in connection
Loneliness raises mortality risk on par with smoking. The Blue Zones aren't about diet; they're about people. Schedule the dinner. Call the friend. It's longevity work.

A weekend checklist
The shortlist of moves that delivers most of the benefit. Pick one, finish it, then come back for the next.
- Annual bloodwork: ApoB, Lp(a), fasting insulin, hs-CRP, HbA1c
- Resistance training 2–3× per week, progressively loaded
- Zone 2 cardio 180+ min/week + one VO₂ max session
- 1g of protein per pound of lean body mass daily
- Weekly in-person time with people you care about
Frequently asked
Are longevity supplements (NMN, rapamycin, etc.) worth it?+
Most are early-stage science in humans. None come close to the proven impact of strength training, cardio, sleep, and metabolic health. Master the basics before optimizing the margins.
What's the right age to start longevity work?+
Right now. Every decade you delay strength training is roughly 5% of muscle mass you have to fight harder to reclaim later. The compounding works in both directions.
Is alcohol really that bad?+
There is no longer a credible 'protective dose.' Less is better; none is best. If you drink, treat it as a deliberate indulgence — not a daily habit.
