Why Aging Does Not Come Suddenly One Day

This piece is the complete Chapter 1 of Stones in the Body: More Frightening Than Cancer (Yoon Jong-won). It is a narrative containing the author's academic hypothesis, and the body, figures, and citations follow the manuscript as written.

Our body takes countless injuries every single day, yet at the same time an astonishingly precise 'repair system' is fixing them without rest. Cells divide, damaged proteins are cleared away, DNA is repaired, and inflammation too subsides, keeping the balance.

When we are young, this repair speed is faster than the speed of damage, so even if we push ourselves too hard for a day, we recover by the next day. Even if a little calcium leaves the bones, it is replenished right away, and even if a little calcium builds up on the vessel wall, it is dealt with before it hardens into calcification.

But as we grow older, this repair speed gradually slows down. The calcium that has left is not fully replenished, and the calcium built up on the vessel wall hardens into calcification without being dealt with. A little today, a little tomorrow. The small traces that were not fixed, that is, the calcium lost from the bones and the calcification piled up in the soft tissue, remain here and there throughout the body. These pile up and pile up until one day the blood vessels are blocked, the joints stiffen, and the bones collapse.

The Age That Grows Old on the Outside, the Body That Collapses Within

If we redefine aging, in the end it is the road toward natural death.

Think of an old apartment building. Small cracks form in the walls, rust sets into the plumbing, and the electrical wiring ages. At first it passes by as if it were nothing much. But at some moment the maintenance costs and repair bills spike all at once. Our body is the same.

Stress, poor eating habits, repeated infections. These create invisible micro-damage, and that damage piles up steadily over a long time. Inflammation and calcification settle into the blood vessels, in the joints the cartilage wears down and grows stiff, in the teeth the enamel wears away and the gum bone sinks so that the teeth turn sensitive and loose and then fall out. Holes form in the bones throughout the body so that the pillars of the body collapse into osteoporosis and fractures, and calcium floods into the brain so that nerve cells die and memory declines. The immune system malfunctions and even attacks its own body.

At first it reveals itself as minor symptoms that we brush off, thinking 'it must be my age.' But as time passes it erupts in earnest as chronic diseases that carry names like arthritis, diabetes, hypertension, myocardial infarction, dementia, osteoporosis, and cancer. Aging is the process in which all of this accumulates and leads to systemic decline and natural death.

The Fire That Will Not Go Out and the Stone That Hardens, the Two Faces of All Disease

Now, rather than seeing the chronic diseases that blanket the later years, arthritis, diabetes, heart disease, dementia, osteoporosis, and cancer, as diseases each standing apart, follow their roots down deep. In the end, two things sit at their center. Chronic inflammation that will not go out and continues for a long time, and calcification spread throughout the whole body including the blood vessels.

Why does inflammation, once it catches fire, not easily settle down but last so long, as if burning every corner of the body? Why on earth does this calcification form, and where did it flow in from?

Even as we pride ourselves on living in an age of advanced medical science, we still cannot clearly answer this question with a single integrated view. Life itself has been extended longer than before, but the price is that we must live alongside chronic disease, taking medicine for a lifetime. 'Living long in sickness,' that is, living long but living with disease, has become the portrait of old age in our time. It looks like an unavoidable reality.

The Question That Overturns the Board

But if the story ended here, we could only remain a generation that hurts a little longer and then departs. So at this point a question arises.

"Buildings and cars, if we inspect them on time and fix the damaged parts in advance, last much longer without major breakdowns, so can our body really not do the same?"

What if we could properly understand how this chronic inflammation and calcification form inside the body and where they flow and spread, their hidden pathways and mechanisms? What if we could block and suppress them from the earliest stage when the spark is lit?

We would be able not merely to live long, but to extend far more the healthy lifespan, the period free of illness. We would be able to draw much closer to a long life free of disease, living without being tormented by illness even as we age.

It is precisely to answer this board-overturning question that this book presents the DIAH-7M Aging and Chronic Disease Pathway System. It is the world's first map that has systematized the process and pathway of aging and chronic disease.

It lays out as a single map the entire process by which the chronic diseases called arthritis, diabetes, heart disease, dementia, osteoporosis, cancer, and the like begin from small abnormal signals, pass through worsening and complications, and finally reach death.

DIAH-7M: The World's First! The Aging and Chronic Disease Map Revealed

DIAH-7M is not yet a theory registered as an official term in academia, but the author's integrated interpretive frame that rearranges the countless already-known medical facts into a single flow.

1. One Root, Hundreds of Branches

Arthritis, diabetes, hypertension, heart disease, dementia, osteoporosis, cancer. These diseases each look like a different illness. Hospitals too treat them separately. Diabetes at endocrinology, the heart at cardiology, the joints at orthopedics, the bones at endocrinology or rheumatology, dementia at neurology. Each has different tests, different drugs, different treatments.

But is it not strange? Why does heart disease so often arise in diabetic patients? Why does dementia so often come to hypertensive patients? Why is arteriosclerosis found together in osteoporosis patients? Why do several chronic diseases rush in all at once upon one person?

For it to be brushed off as 'that's just what happens when you get old,' too many people go through the same pattern. For it to be called coincidence, it is too regular.

The DIAH-7M chronic disease map answers this question. Chronic diseases are not separate illnesses. They are hundreds of branches spreading out from a single root.

That root is DIAH, the branches are 7M, and the chronic diseases are the fruit. M is Mechanism, that is, the way the body breaks down. There are seven ways, so it is 7M.

2. DIAH: The Four Triggers That Rob Calcium from the Bones

DIAH takes the first letters of four triggers. All four produce the same result. Calcium leaves the bones.

D is Deficiency.

When calcium intake is insufficient, the blood calcium concentration drops, and to make up for it calcium is drawn out from the bones. Moreover, the I, A, and H triggers also ultimately induce a deficiency of blood calcium.

I is Inflammation.

The inflammatory response consumes calcium in large amounts, and it is replenished from the bones by as much as is consumed.

A is Acidosis.

When the body becomes acidified, the alkaline bone calcium is mobilized to neutralize it.

H is Hypoxia.

When oxygen is lacking, the cell's energy production falls, and as the calcium pump fails to do its job, the calcium balance inside and outside the cell is greatly shaken. If this process continues for a long time, it affects hormones and kidney function so that the balance between bone and blood calcium also collapses, and it acts in the direction of mobilizing more calcium from the bones.

Abbreviation	English	Meaning	Action	Explanation
D	Deficiency	Deficiency	Bone calcium fills the shortfall	Deficiency of calcium, minerals, vitamin D, and so on → bone calcium is broken down to replenish → blood → supplied to various cells ※ Common: D, I, A, H all induce a drop in blood calcium, which is replenished by breaking down calcium from the bones.
I	Inflammation	Inflammation	Calcium is mobilized to put out inflammation	The inflammatory response consumes calcium in large amounts → bone calcium is broken down to replenish → blood → concentrated at the inflammation site
A	Acidosis	Acidosis	The bones are sacrificed to neutralize acid	Alkaline calcium is used to neutralize acid → bone calcium is broken down to replenish → blood → whole-body pH balance
H	Hypoxia	Hypoxia	Under oxygen shortage, calcium floods into the cells in excess	Cellular oxygen shortage → calcium pump failure → blood calcium over-absorbed into the cells → blood calcium deficiency → bone calcium broken down to replenish → blood → reabsorbed by the damaged cells → vicious cycle

Whether calcium deficiency, inflammation, acidosis, or hypoxia. The pathways differ but the result is the same. Calcium leaves the bones.

3. 7M: The Seven Mechanisms by Which Leaked Calcium Breaks Down the Body

Where does the calcium that has left the bones go? It piles up in the soft tissue. On the vessel walls, in the joints, on the valves, at the secretory openings, inside the cells. The calcium piled up this way breaks down the body in seven ways.

Mechanism	Name	English Name	Action	Scope
1M	Obstruction and Bursting	Obstruction & Rupture	It blocks and bursts	Calcification deposits → lumen obstruction, stenosis, infarction, rupture, hemorrhage
2M	Dulling	Dysfunction	It grows dull	Calcification deposits → dulling of joint/muscle/valve movement, decline of contraction/relaxation function
3M	Coating and Blockage	Coating & Blocking	It is coated and blocked	Calcification deposits → receptor blocking, signal blocking, secretion blocking, insulin resistance
4M	Hardening	Hardening	It hardens	Calcification deposits → fibrosis, calcification, rigidity, loss of elasticity
5M	Overflow and Bursting	Overflow & Burst	It overflows and bursts	Excess calcium influx → cell overproliferation, hypertrophy, tumor, swelling, apoptosis
6M	Disconnection	Disconnection	It is cut and severed	Calcification deposits → nerve severance, vessel occlusion, tissue necrosis, apoptosis
7M	Collapse	Collapse	It falls apart	Calcium deficiency → structural collapse of hard tissue (bone, teeth)

1M is Obstruction & Rupture (it blocks and bursts). Calcification builds up in the blood vessels so that the inner diameter narrows and then blocks, or the vessel wall weakens and bursts. Myocardial infarction, cerebral infarction, and cerebral hemorrhage belong here.

2M is Dysfunction (it grows dull). Calcification deposits in the joints and muscles so that movement grows stiff. Knee arthritis, degenerative disc disease, facet joint arthritis of the spine, calcific tendinitis of the shoulder, and heart valve disease are representative.

3M is Coating & Blocking (it is coated and blocked). In the process by which the passages through which hormones are secreted and the receptors that receive them lose their function and go dead, inflammation, fat accumulation, fibrosis, microcalcification, and the like act together. Diabetes, insomnia, and hypothyroidism are representative diseases related to this kind of signal blocking.

4M is Hardening (it hardens). Calcification deposits in the tissue in large amounts so that it hardens stiff. Frozen shoulder, arteriosclerosis, and valve calcification belong here.

5M is Overflow & Burst (it overflows and bursts). When a cell falls into a hypoxic state, the calcium channels break down so that blood calcium floods into the cell in excess. Because of this the cell overproliferates or dies from overload. Tumors and dementia are this pathway.

6M is Disconnection (it is cut and severed). Nerves are blocked or severed so that the tissue dies. Alzheimer's, diabetic foot necrosis, and macular degeneration apply here.

7M is Collapse (it falls apart). The bones and teeth from which calcium has left develop holes and grow brittle and collapse. Osteoporosis, osteoporotic fracture, periodontitis (alveolar bone resorption), and otolith dizziness are representative.

4. Chronic Disease Read Through a Single Formula

If we organize all of this into a single formula, it is this.

Trigger factors such as reduced calcium absorption, stress, infection, processed food, and lack of exercise → DIAH (four triggers) activate → bone calcium efflux → 7M (seven pathological mechanisms) → chronic disease

Diabetes, hypertension, heart disease, dementia, osteoporosis, cancer. The names differ but they follow the same pathway. DIAH robs calcium from the bones, and the robbed calcium breaks down every part of the body through 7M. This is the whole picture of the DIAH-7M chronic disease and aging pathway system.

The Truth the Statistics Tell, the Common Thread of the Top Ten Causes of Death

Can DIAH-7M really explain chronic disease? However plausible a theory looks, it is useless if it does not fit reality. Let us verify it with official statistics.

According to Statistics Korea's 2024 causes of death statistics, the top ten causes of death are cancer, heart disease, pneumonia, cerebrovascular disease, suicide, Alzheimer's disease, diabetes, hypertensive disease, liver disease, and sepsis. These ten account for about 67% of all deaths.

If we look at the nine excluding suicide from the DIAH-7M perspective, a striking common thread emerges. Heart disease and cerebrovascular disease are calcification building up in the blood vessels so that they block or burst (1M Obstruction & Rupture). Hypertension is the blood vessels hardening (4M Hardening). Diabetes is the process in which a disturbance of the calcium signaling system produces insulin resistance, or the beta cells are excessively stimulated until they tire and are damaged (3M Coating & Blocking, 5M Overflow & Burst). For Alzheimer's too, in addition to protein aggregation, inflammation, and vascular factors, a 'calcium hypothesis' has been proposed, that nerve cells slowly die as calcium floods in excess inside and outside the brain cells (5M Overflow & Burst → 6M Disconnection).

Cancer is a disease in which cells proliferate without stopping as multiple factors such as genetic mutation, inflammation, and metabolic disturbance overlap, and research is increasing that a disturbance of the calcium signaling system acts as an important axis in that process (5M Overflow & Burst). Pneumonia and sepsis are on the surface acute infections, but they are closer to a 'final crack' that acts as a fatal single blow in a body already weakened by chronic inflammation and immune aging.

If we look again at the nine diseases from the DIAH-7M perspective, we can confirm that most of them lie on the common pathway of 'deficiency, inflammation, acidosis, hypoxia → calcium metabolism abnormality and calcification deposition.'

There is a further point worth noting. Compared with 2014, the death rates of diseases like Alzheimer's, sepsis, and pneumonia have risen from 1.5 times to more than 2 times over ten years. All three of these diseases are the final stage of a pathway that begins in chronic inflammation, passes through calcium metabolism abnormality, and ends in tissue damage.

The causes of death by age are also significant. From the teens to the thirties suicide ranks first, but from the forties onward cancer ranks first. This shows that the DIAH-7M pathway is time-dependent. The young have not yet accumulated calcium efflux and calcification deposition, and from the forties onward the damage piled up over decades surfaces.

It is the same when we look at World Health Organization data. Ischemic heart disease, stroke, chronic obstructive pulmonary disease, and lower respiratory infections have been the top causes of death, unchanged for more than thirty years since 1990. Medicine has advanced dazzlingly, so why does the ranking not change? Because modern medicine is good at "clearing blocked blood vessels" but cannot approach the root cause of "why they block."

What the official statistics tell us is clear. The top ten causes of death look each their own on the surface, but from the DIAH-7M perspective they are branches split from a single root.

Why Modern Medicine Cannot Solve Chronic Disease 1. Strong Against Acute Disease, Weak Against Chronic Disease

Modern medicine has produced miracles. It conquered infectious disease with antibiotics, removes cancer with surgery, and saves cardiac arrest patients with emergency care. Before acute disease, modern medicine is overwhelming.

But before chronic disease it cannot exert its power. It cannot "cure" diabetes. It cannot "eradicate" hypertension. It cannot "reverse" arthritis. It only "manages" while taking medicine for a lifetime.

Why is that? Because acute disease and chronic disease are different in nature. Acute disease has a clear cause. A germ entered, a vessel blocked, a bone broke. Remove the cause and it heals. Kill the germ with antibiotics, open the vessel with a stent, fix the bone with a cast.

Chronic disease is different. There is not one cause. It progresses slowly over decades. Invisible micro-damage piles up and up until one day it "breaks out." By the time it breaks out, the damage has already progressed considerably. Even if we try to remove the cause, it is hard to pinpoint what the cause is.

2. It Sees the Symptom but Not the Pathway

Modern medicine sees the symptom. If blood sugar is high, it gives a drug to lower blood sugar. If blood pressure is high, it gives a drug to lower blood pressure. If cholesterol is high, it gives a drug to lower cholesterol. If a joint hurts, it gives a painkiller. The symptom is caught. But the disease keeps progressing.

Why? Because the symptom is a result, not a cause. High blood sugar is a result of diabetes, not a cause. High blood pressure is a result of a vascular problem, not a cause. If we press down the result, the number improves, but the cause stays as it is. Since the cause stays, the disease keeps progressing.

What modern medicine is missing is the "pathway." Where it begins, in what order, how it progresses. Since it does not know this pathway, it cannot know where to cut it. Since it does not know the point to cut, it only cleans up the result that has already burst.

3. It Sees Disease by Splitting It Apart

Modern medicine splits disease apart. Diabetes at endocrinology, hypertension at cardiology, arthritis at orthopedics, osteoporosis at endocrinology, dementia at neurology. Each department sees its own disease.

The advantage of specialization is clear. It can go deep. But it has a disadvantage too. The connection is cut. When a diabetic patient gets heart disease, it is called a "diabetic complication." When arteriosclerosis is found in an osteoporosis patient, it is called a "comorbidity."

But it cannot explain why they complicate, why they accompany. They are branches from the same root, but seeing only the branches separately, the connection is not seen.

From the patient's side it is frustrating. Getting diabetes drugs at endocrinology, blood pressure drugs at cardiology, joint injections at orthopedics, dementia drugs at neurology. The drugs increase, the days of going to the hospital increase, and yet the body does not get better. It is only managed.

4. It Cannot Explain Slow Aging

Aging sometimes progresses fast and sometimes slow. At the same age of 70, some people are as healthy as 60 and some are as frail as 80. Why is that?

Recently the concept of "slow aging" has been drawing attention. Slow aging does not mean 'aging can be stopped,' but that through already-known lifestyle habits and metabolic control, the speed of aging and the speed of chronic disease progression can be slowed.

In other words, keeping the biological age younger than the calendar age. Put the other way, certain factors accelerate aging.

But modern medicine cannot explain the mechanism of slow aging in an integrated way. Antioxidation is important, inflammation must be reduced, blood sugar must be managed, exercise must be done. Each piece of advice is correct. But why it is so, how they connect, there is no integrated picture.

Does taking antioxidants slow aging? Some studies say yes, some say no. Does reducing inflammation prevent chronic disease? To some extent yes, but not completely. There is information scattered piece by piece, but there is no thread that strings it into one.

DIAH-7M is a map that reconstructs this slow-aging strategy from the perspective of the four triggers of deficiency, inflammation, acidosis, and hypoxia, and of calcium metabolism.

Living Long in Sickness, an Age That Grows Old Alongside a Bag of Pills

The reality created by the limits of modern medicine is living long in sickness. We live long, but we live with disease.

Average life expectancy has passed 80. But healthy lifespan is around 65. We live the last 15 years and more of life going in and out of hospitals, taking pills by the handful, with the body uncomfortable.

Is this the best we can do? Medicine has advanced, they say, so why do chronic disease patients keep increasing? Drugs have gotten better, they say, so why do more people take drugs?

Modern medicine has achieved remarkable results against acute disease, but chronic disease is even now an object of lifelong management rather than 'cure.' The World Health Organization and the health authorities of each country likewise classify non-communicable chronic diseases as objects of 'long-term management and prevention' rather than 'treatment.'

This book is an attempt to supplement the 'view that sees the pathway' that is being missed in between.

Why DIAH-7M Is Needed 1. When the Pathway Is Visible, the Point to Cut Is Visible

DIAH-7M shows the pathway of aging and chronic disease. Where it begins, in what order, how it progresses.

When the pathway is visible, the point to cut is visible. If we cut at the stage where the DIAH triggers operate, calcium does not leave the bones. If calcium does not leave, 7M does not operate. If 7M does not operate or is delayed, chronic disease may not occur or may be delayed.

7M is not a sequence that proceeds in order from 1 to 7. Depending on the type of DIAH trigger and the site where calcium deposits, each M occurs independently.

If it builds up on the vessel wall it becomes 1M (blocking and bursting), if it builds up in the joints it becomes 2M (growing dull), if it builds up on the cell's signal receptors (the sites that receive hormones, neurotransmitters, and so on) it becomes 3M (coated and blocked), and so on. Therefore, if we improve the DIAH environment, we can cut or delay the pathway of whichever M is currently in progress.

Not temporarily pressing down the symptom with drugs as in symptomatic treatment, but cutting the pathway itself. This is the heart of DIAH-7M.

2. When the Connection Is Visible, Integrated Management Becomes Possible

DIAH-7M shows the connection among chronic diseases. Why diabetes, hypertension, heart disease, and osteoporosis come together upon one person. Because they are different branches (7M) from the same root (DIAH).

When the connection is visible, integrated management becomes possible. Not diabetes drugs separately, blood pressure drugs separately, osteoporosis drugs separately, but responding to several diseases at once with a single strategy that blocks the DIAH triggers.

Solving D (Deficiency) is good for diabetes, for osteoporosis, and for heart disease. Reducing I (Inflammation) is good for arthritis, for dementia, and for cancer. Govern the one root and the several branches grow healthy together.

3. It Explains the Mechanism of Slow Aging

DIAH-7M explains the mechanism of slow aging. Why some people age fast and some age slowly.

When the DIAH triggers operate strongly, frequently, and for a long time, we age fast. Calcium leaves much, often, and long. 7M progresses fast.

Chronic disease comes early, in numbers, and severely. When the DIAH triggers operate weakly, rarely, and briefly, we age slowly. Calcium efflux is minimized. 7M progresses slowly. Chronic disease comes late, in few numbers, and lightly.

Slow aging is not an abstract concept. It is a concrete practice of reducing the DIAH triggers and slowing the progress of 7M.

The End of Living Long in Sickness, the Beginning of a Long Life Free of Disease

Living long in sickness, created by modern medicine. A life lived long but alongside disease. DIAH-7M presents the possibility of changing this.

If we block the DIAH triggers early, we can reduce the very occurrence of chronic disease. Even if chronic disease is already present, we can slow the progress to the next stage. We can prevent complications. A long life free of disease. A life not tormented by illness even as we age. A life that narrows the gap between healthy lifespan and average lifespan. DIAH-7M is the map to that possibility.
