Overdose on simplicity.
Your body doesn't need hacking. It just wants the inputs evolution tuned it for: light, movement, real food, people and darkness. The rest is noise.
ApoB
The count of atherogenic particles — you stop plaques before they start.
Visceral fat & HbA1c
You avoid insulin resistance and tissue degradation.
hs-CRP
You switch off silent systemic inflammation.
Cortisol
Sharply up in the morning with light. Down to zero at night with darkness.
Anchor
15–30 min walking outside right after waking (even a lousy 10 minutes beats staring at your phone). Water + electrolytes. A protein-rich breakfast, then D3 + K2 and omega-3. 3–5 g of creatine if you like.
Brain
Kill algorithmic feeds, isolate your attention, do the hardest work of the day. Create, learn, write, think. And read.
Engine and armour
Eat food in its evolutionary form; simple carbs are a good servant and a bad master. Heavy weights 2–3× a week. Zone 2 once a week, intervals once a week (10–30 s all out / 2 min easy, 5×) — that's your VO₂max.
Wind down
Forget performance, this time belongs to your tribe. Sauna, cold, breathing or silence. Cut dopamine 1–2 h before bed; magnesium bisglycinate. Sleep in absolute darkness, silence and cool.
Focus
Fluid (5) or fragmented (1)?
Vitality
Light and energetic (5) or lethargic (1)?
Perspective
Calm in chaos (5) or stressed (1)?
Wind-down
Unplugged (5) or wired (1)?
Don't sweat one bad day. Watch the rolling 7-day average. You're building a system that compounds over decades.
