The new book by Dr Kostas Pisios
After the Retreat
You came back rested, clearer, lighter. Then the calendar filled again. This is a physician's book about what actually changed in you — and what it needs from you now.
Inside the book
Written for the weeks that follow
Three movements, read at the pace of an ordinary week.
01
What actually changed
Rest, attention, sleep, appetite, mood — the retreat moved several things at once. The first part separates what shifted from what simply felt different.
02
Why it fades
Nothing failed. The conditions changed. A physician’s explanation of why the first ordinary fortnight undoes so much of it, without blaming your discipline.
03
What to keep
Not a programme. A small number of things worth protecting, chosen because they survive a normal week — and a way to tell whether they are holding.
Two editions
The same book, two ways to receive it
One you buy for yourself. One a premium partner gives you as you leave.

Premium partner package
The Premium Retreat Edition
A premium printed edition prepared for retreats, hotels and travel advisers to give their guests — the last thing they are handed, and the first thing they open at home.
The package is arranged with the partner, not sold on this page. If you run a retreat, a hotel or an advisory practice, the guest package is set up through the partner routes.
The 14-day Return Home Companion
A printed companion for the fourteen days after departure — a short daily place to record what is holding and what is slipping. It belongs only to the premium partner package. It is not included with the Amazon edition.
Thirty days of Longivy Pro
Selected premium partner guests can request 30 days of Longivy Pro, so the fortnight in the companion has a Wellness Score beside it. The pass is requested with the email used — or intended for use — for the Longivy account.
Your partner sends the guest pass link with the package.
The return home
The retreat ends. The fortnight begins
Most of what a retreat gives you is decided in the two weeks after it, at home, with the same commute and the same evenings. The book is written for that stretch — calmly, and without asking you to rebuild your life.
Days 1-3
Everything still feels close. The book asks you to write down what you noticed, before it blurs.
Days 4-10
The calendar returns. This is where the reading turns practical — which one or two things are worth protecting.
Days 11-14
You look back at your own notes rather than at the retreat. What held, and what quietly went.
The book and the app
What the book asks, Longivy measures
Longivy is the physician-developed app by the same author. Reading it is optional either way — the book stands on its own, and the app keeps the question open.
One score, six dimensions
Emotional state, energy, sleep and lifestyle read together — the same whole-person view the book takes.
A check-in, not a device
Under 30 seconds a day, from your phone. No wearable required to see the trend.
Weeks, not moments
The fortnight after a retreat is a trend, and a trend is the one thing memory is bad at holding.
