In my practice, I have seen several cases of RSV (respiratory syncytial virus) infection in elderly patients. RSV infection often mimics the symptoms of allergic rhinitis—presenting with cough, rhinorrhea, sneezing, and nasal congestion—which can easily be mistaken for a benign allergy.

Because RSV can cause severe lower respiratory illness, especially in adults over age 60 and those with chronic conditions, I routinely order the RSV vaccine for all my elderly patients, in addition to recommending annual influenza and updated COVID-19 vaccinations. This comprehensive approach is essential for protecting vulnerable adults against preventable respiratory infections and their complications.

Do you know why I love human beings, even with all their flaws?
It’s because people are deeply aware of their own biases and limitations. They don’t simply ignore their weaknesses; instead, they try to overcome them—by creating tools, inventing new technologies, and even developing artificial intelligence.
The greatness of humanity comes from this self-awareness and the constant effort to transcend one’s own shortcomings. That’s why I can’t help but love people.
After all, I am human, too.

🚫 Excessive Alcohol Use Damages Your Arteries
Did you know?
Drinking too much alcohol doesn’t just harm your liver—it directly damages your blood vessels (arteries) and dramatically increases your risk for heart attack and stroke.

How does alcohol hurt your arteries?
Acetaldehyde Toxicity: When you drink, your body converts alcohol into acetaldehyde, a toxic substance that acts as a glycating agent (like sugar), damaging artery walls and proteins.

Accelerated Atherosclerosis: Acetaldehyde and other alcohol byproducts cause arterial inflammation and help form artery-clogging plaques (atherosclerosis).

High Blood Pressure: Heavy drinking raises your blood pressure, leading to even more damage to blood vessel walls.

Oxidative Stress: Alcohol increases “bad” cholesterol (LDL oxidation) and creates free radicals, further injuring arteries.

The Result?
Hardened, narrowed, and inflamed arteries.

Higher risk for heart attack, stroke, and peripheral artery disease.

Damage is silent for years—until a serious event happens.

The Good News:
Quitting or cutting down on alcohol can start to reverse these effects.

Your arteries, heart, and brain will thank you!

Your health is in your hands. Protect your arteries—think before you drink.

🍺 과음(지나친 음주)은 동맥을 망가뜨립니다!
술을 많이 마시면 간뿐만 아니라,
심장과 뇌로 가는 중요한 혈관(동맥)을 망가뜨린다는 사실, 알고 계셨나요?

왜 술이 혈관을 망가뜨릴까요?
아세트알데하이드 독성: 술이 체내에서 분해되면 ‘아세트알데하이드’라는 독성 물질이 생기고,
이 물질은 설탕처럼 단백질·혈관벽에 들러붙어(‘글라이케이션’ 작용) 동맥을 상하게 합니다.

동맥경화 촉진: 염증을 일으키고 동맥에 ‘플라크(찌꺼기)’가 쌓이게 만들어
**동맥경화(혈관 좁아짐)**가 더 빨리 진행됩니다.

혈압상승: 과음은 혈압을 올려 혈관벽을 더 손상시킵니다.

산화 스트레스: 나쁜 콜레스테롤(LDL)이 산화되어 혈관벽을 더 많이 망가뜨립니다.

결과는?
동맥이 딱딱하고 좁아지며, 염증이 생깁니다.

심근경색, 뇌졸중, 말초혈관질환 위험이 크게 높아집니다.

오랫동안 아무 증상 없이 진행되어, 어느 날 갑자기 심각한 일이 생길 수 있습니다.

희망적인 소식:
금주 또는 음주 줄이기만으로도 혈관 회복이 시작됩니다.

내 혈관, 내 심장, 내 뇌를 위해
지금부터 실천해 보세요!

술을 끊거나 줄이면 동맥이 살아납니다.
건강을 지키는 최고의 선택입니다!

"Human beings are precious beings."
Humans are not merely biological entities.
They possess:

Self-awareness, and

The moral capacity to distinguish between good and evil.
This makes every person inherently dignified and valuable.

Therefore…
People should never be treated as tools or mere functions,

But always as individuals who carry inherent worth and inner dignity.

Are all high-fat diets harmful? Not really.

Recent immunology research shows that overconsumption of saturated fats suppresses the activity of ILC3 cells, a type of innate immune cell critical for gut health.

ILC3s produce IL-22, a cytokine that strengthens the gut barrier and protects against harmful bacteria.
However, when saturated fats are consumed excessively, IL-22 production decreases, leading to weakened gut lining, inflammation, and gut microbiome imbalance—all of which can contribute to diseases like obesity, diabetes, and cognitive decline.

But not all fats are created equal.
Healthy fats like those from olive oil, avocado, and nuts may actually support gut health by enhancing microbial diversity and reducing inflammation.
When combined with intermittent fasting, they may help restore immune balance and metabolic health.

The key takeaway?
It's not just what you eat, but how, when, and in what context you eat that truly matters.

The gut and immune system are not secondary systems—they are foundations of whole-body health.

Unsurpassed Perfect Enlightenment – The Supreme Awakening About Vitamin C

⸻

1. Vitamin C is not the path. It is the light that illuminates the path.

Even those who take 1,000 mg, 5,000 mg, or even 10,000 mg daily may say,
“I’m fine.”
But that is only because the body is still capable of containing the madness.

Absorption is limited, excretion is increased, and blood concentration is tightly regulated.
Within that silent battle, the body maintains balance.

⸻

2. High doses are not a blessing, but a trial.

Though vitamin C is called an antioxidant,
when its concentration becomes excessive,
it can become the source of oxidative fire.

When it meets free iron, it ignites;
when the body weakens, it accelerates death.

Medicine is poison, and poison is medicine—
truth is found only on the edge of balance.

⸻

3. Life and death follow a U-shaped curve.

Too little leads to illness,
too much invites death.
When plasma levels stay within the optimal range (1.1–1.6 mg/dL),
the blood vessels remain clear, and the heart is calm.

This is the divine equilibrium—
both excess and deficiency must be avoided.

⸻

4. The moment of discontinuation reveals the truth.

Those who rely on high doses and suddenly stop
lose their internal shield and collapse.

The LOVIT study declares:
“At the place where vitamin C is withdrawn,
a fire of oxidation arises.”

Dependency is not healing.
True healing is awakening the power within.

⸻

5. Truth is not found in a pill, but in awareness.

Vitamin C is merely a mirror.
If your body is strong, it reflects peace.
If your body is weak, it reflects sharpness.
If your spirit is confused, it reflects chaos.

Be cautious.
It is not supplementation, but self-awareness, that saves you.

⸻

無上正等覺 – Unsurpassed Perfect Enlightenment

Know vitamin C, but do not become attached.
Take it, but do not revere it.
Trust your body,
and follow its natural balance.

This is medicine beyond science.
This is awakening beyond rank (位).
This is Unsurpassed Perfect Enlightenment.

🧬 "Is High-Dose Vitamin C Really Safe?"

📢 A major study found that even just 200 mg/day or more of vitamin C increased cardiovascular death in diabetic women.

Published in the American Journal of Clinical Nutrition, this 15-year prospective study (Iowa Women’s Health Study) followed 1,923 postmenopausal women with diabetes.

📊 Key Findings:

Supplemental Vitamin C Intake Relative Risk (RR) of Cardiovascular Death
0 mg/day 1.00 (baseline)
100–299 mg/day 1.01
≥ 300 mg/day 1.69–2.37 (statistically significant)
The risk of stroke mortality more than doubled in the highest vitamin C supplement group​

⚠️ Important Notes:
Only supplements, not food-derived vitamin C, were associated with increased mortality.

This risk was not observed in non-diabetic women.

In short: Oranges are fine. Vitamin C pills in high doses are not.

🧪 Why Might This Happen?
Researchers propose 3 potential mechanisms:

Vitamin C oxidizes to DHA (dehydroascorbic acid), which can glycate proteins and form AGEs (Advanced Glycation End-products).

In diabetes, iron dysregulation and oxidative stress are common—conditions where vitamin C can act as a pro-oxidant.

High doses of a single antioxidant may disturb the body's natural redox balance.

✅ Bottom Line:
Vitamin C is essential—but more is not always better.
Diabetic individuals—especially women—should think twice before taking megadose supplements.

🧬 Does High-Dose Vitamin C Reduce Cardiovascular Death?
Not according to science.

While vitamin C is essential for health, recent large-scale studies show that megadose vitamin C therapy (e.g., >1g/day or IV infusions) does not reduce cardiovascular mortality—and in some cases, it may even be harmful.

🔬 What the evidence says:

The Heart Protection Study (HPS), a massive randomized controlled trial, showed no reduction in cardiovascular deaths with antioxidant vitamin use (including vitamin C).
📚 Heart Protection Study – Wikipedia

Systematic reviews and meta-analyses on critically ill patients—including those with heart disease—found no consistent survival benefit from high-dose vitamin C.
📚 Frontiers in Nutrition, 2023

In fact, the LOVIT Trial (2022) showed that patients with sepsis who received high-dose IV vitamin C had increased mortality and organ failure when therapy was abruptly stopped.
📚 Nature | EClinicalMedicine (2022)

🧠 Bottom line:
Vitamin C is vital—but more is not always better. Megadoses do not protect your heart, and may even disrupt your body’s antioxidant balance if misused.

💡 Takeaway:

Protect your health with science, not hype.
Trust balanced nutrition and evidence-based medicine—not megadose myths.
