The preview opens the door — Chapter 1 in full, and a guide to everything inside. Here is what waits in the complete edition.

Ch. 3 · The Five Levers Most Couples Never Touch

The complete framework: the five inputs that decide how you age — and how to pull each one as a team.

Ch. 5 · The Hormone Advantage

Food, intimacy, and the couple's edge — the lever most health books reduce to a single sentence, fully opened.

Ch. 6 · The Fertility Window

The 90-day His & Hers protocol and the science of egg and sperm quality, together.

Ch. 7 · The Collagen Code

How your body builds its own collagen — and the precise pairing that doubles it. The famous Collagen Window.

Ch. 9 · The Plate for Two

One plate, built with your eyes closed, that pulls all five levers at once.
