⏳ Aging is inevitable, but you can slow it down. Longevity isn't about living forever—it's about living better, longer and with more vitality.

What if you could decode the secrets of cellular rejuvenation and transform your health trajectory?

🧬 Vitality is the essence of life itself. It's the capacity to thrive, adapt, and maintain optimal function despite environmental challenges. 

However, vitality isn't given—it is cultivated through understanding the complex interplay between our biology, environment and lifestyle choices. Just as the phoenix bird rises from the ashes and is reborn with renewed strength, you can also experience cellular regeneration through evidence-based interventions.

Mastering longevity leads to a more vibrant, energetic, and fulfilling life.

Longevity is an integral part of HOLOLIFE—from Greek "holos" meaning "whole" or "complete"—which takes biohacking and personal development to the next level, combining self-optimization with a mission to build a better world. 

Rooted in becoming the best version of oneself, HOLOLIFE emphasizes self-improvement for personal benefit, serving others and making a positive global impact.

From the authors of Biohacker's Handbook & The Resilient Being comes the most ambitious, literate, and illustrative scientific review to date, combining the science of longevity with practical biohacking strategies. Medical Doctor from the University of Helsinki / Science Author Olli Sovijärvi, and Futurist and technologist Teemu Arina 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 1000+ up-to-date scientific references. You will learn everything you need to know to become a Vital Being.

The HOLOLIFE book series delves into the multifaceted nature of human optimization, exploring how individuals can adapt, thrive, and extend their healthspan in the face of modern challenges.

The Vital Being is the second volume in this groundbreaking series. It focuses on the biological and physiological mechanisms that govern aging and immunity. These fundamental processes determine how we age and how we can intervene to maintain vitality throughout life.

The book series also highlights the experiences and deep knowledge of its authors, ranging from theoretical facts and data to experimental protocols and practical details, helping readers become the most vital version of themselves.
