The Vital Being
Decoding the Mastery of Longevity & Vitality
Aging is inevitable, but the rate of it is not. This is the biology of getting older, from a single mitochondrion up to whole-body systems, and what the evidence says you can actually do about it.

Mastering HOLOLIFE
Vitality is cultivated, not given
Longevity is not about living forever. It is about living better, for longer, with more capacity to thrive, adapt and keep functioning well under load.
That capacity comes from the interplay between biology, environment and the choices made daily. Just as the phoenix is reborn from the ashes with renewed strength, cellular regeneration is something the body does, and something evidence-based interventions can support.
Longevity is an integral part of HOLOLIFE, from the Greek "holos" meaning whole or complete, which takes biohacking beyond optimizing single parts and into the system they belong to.
The book
An essential masterpiece for extending healthspan
From the authors of Biohacker's Handbook and The Resilient Being comes the most ambitious, literate and illustrative scientific review to date, combining the science of longevity with practical biohacking strategies. Olli Sovijärvi, medical doctor from the University of Helsinki and science author, and Teemu Arina, futurist and technologist, summarize and illustrate how you can master the biology of aging: from the level of a single mitochondrion up to whole-body systems.
The book includes hundreds of illustrations backed by more than 1000 up-to-date scientific references. You will learn what you need to know to become a Vital Being.
The HOLOLIFE series explores how people adapt, thrive and extend healthspan against modern challenges. The Vital Being is the second volume, and it focuses on the biological and physiological mechanisms that govern aging and immunity: the processes that determine how we age, and where it is possible to intervene.
The book is also a piece of art
Every chapter is illustrated. The design carries the argument rather than decorating it.

The authors
Who wrote it
Two authors, each covering a different half of the problem: the clinic and the technology.
Dr. Olli Sovijärvi, M.D.
Medical doctor and science author
A medical doctor from the University of Helsinki who moved from conventional practice into preventive and holistic medicine. He handles the physiology throughout the book: the mechanisms of aging and immunity, what the evidence supports, and where the honest limits of it are.
Teemu Arina
Futurist and technologist
A technologist, entrepreneur and speaker who has spent two decades on the boundary between people and machines. He covers measurement and intervention: the testing, the self-quantification, and the judgement about which biomarkers are worth acting on.
