THE journal

How old you are matters less than how old your body feels. Your chronological age is merely a number on your passport; your biological age tells the real story: how well your body functions, how much energy you have, and how resiliently you age.

THE longevity journal shows you how to influence that process, with practical insights into nutrition, movement, sleep, stress, and social connection. Theory is complemented by guided prompts and reflection pages that help you actively lower your biological age.

Because what you give attention to, grows.
What you write down, you remember better.
And what you do a little every day, eventually changes everything.

This journal is your tool to turn healthy intentions into daily habits. Fill in the daily pages, track your progress, and feel the change.

Please note THE journal is in Dutch.
