Epilogue: The Small Miracles of Homeostatic Aging

“You can now control the rate of aging!”
If you feel that your body and mind are out of balance, pay attention to this book.

In the age of 100, everyone wants to live long, but in reality, we live with the anxiety of, “Why do I feel like I’m getting old so quickly?”
My health checkup results are generally normal, but I am suffering from chronic fatigue, sleep disturbance, unexplained lethargy, weight gain that is difficult to lose, and recurring pain that is affecting my daily life.
《Homeostatic Aging》 captures this ambiguous gray area with the concept of “accelerated aging,” sharply pointing out the process by which the body’s balance is disrupted at an invisible speed.
Author Park Min-su says that it is not age but “resilience” that determines the speed of aging.
Our bodies have the power to maintain balance, or "homeostasis," even in the face of constant change. However, overtime work, staying up all night, digital overload, processed foods, lack of exercise, and environmental pollution constantly disrupt this system.
This book redefines aging from “treatment after illness” to “how well homeostasis is maintained,” and explains, with a new paradigm, why some people age slowly while others age rapidly, even at the same age.
In an age where “how long and how young you will stay” has become more important than your age in numbers, this book helps readers realize that their daily habits, emotional states, and relationships can either act as an accelerator or a brake on aging.

"Five Cogs to Reverse Aging: The 5M Integrated Strategy"
A practical manual that integrates mind, muscles, intestines, sleep, and cellular energy.

The most significant feature of 《Homeostatic Aging》 is the '5M System' that comprehensively addresses aging.
The five axes of Mind, Myokine, Microbiome, Melatonin, and Mitochondria are viewed as a single network and presented as the '5M Unified Field Theory'.
The idea is that aging can be slowed down only when the mind, which manages stress and emotions, the anti-aging signals secreted when muscles move, the balance of gut microbes, the hormones that control sleep, and the cellular energy factories all work together like interlocking gears.
The message that managing just one thing is not enough and that “homeostasis design” that coordinates all five axes simultaneously is necessary is a point that clearly distinguishes it from existing health books.
Chapters 4-8 present specific strategies for each axis, including mindfulness and 'always mind' training, muscle prescriptions tailored to work and lifestyle patterns, a diet that changes gut microbes, sleep hygiene and light and digital device management, intermittent fasting, and antioxidant routines.
The following nine chapters suggest a 5M integrated routine that can be applied daily, weekly, and monthly, including a morning sunlight routine, a short meditation, meal composition, breathing and stretching during work, evening exercise, and sleep preparation, helping readers immediately apply it to their own lives.
The author asserts, “Aging is inevitable, but I can control the rate at which my body ages.”
This book is a practical aging manual that provides a health roadmap for middle-aged and older adults to plan the next 10 years, and for those in their 30s and 40s, it simultaneously provides warnings and solutions about how their current lifestyle will affect their future healthy lifespan.
