The Healing Power of the Sea- Lumpia Ubod

I often wonder, why I felt good after a swim in our backyard at Chateau Du Mer Beach House in my younger days during our annual winter sojourn in Marinduque, Philippines. The following article fully explained my personal experience why I feel great after swimming in the of ocean of the Amoingon Beach, Boac, Western Marinduque.

Recent scientific evaluations have pointed to ocean immersion as one of the most effective natural methods for regulating the nervous system and absorbing essential minerals. This finding is shifting the perspective of modern wellness, suggesting that blue spaces offer therapeutic benefits that are often more accessible and potent than synthetic alternatives. When the body interacts with the chemical composition of seawater, it undergoes a series of physiological resets that support both physical and mental health. The approach is quickly becoming a cornerstone of environmental medicine for people seeking a natural way to manage stress and mineral deficiencies.
🧠 Balancing the Nervous System
One of the clearest benefits of the ocean is its ability to regulate the nervous system through stimulation of the vagal pathways. Submersion in water, particularly cooler ocean water, triggers the mammalian dive reflex, which slows the heart rate. That shift moves the body from a sympathetic state of fight or flight into a parasympathetic state of rest and recovery. Cortisol levels drop, and the physical symptoms of chronic stress begin to ease almost immediately upon contact with the water.
🔬 The Role of Marine Minerals
The ocean acts as a natural mineral bath containing high concentrations of magnesium, an element involved in hundreds of biochemical reactions. Through thalassotherapy, the skin interacts with these trace minerals, allowing a form of natural replenishment that many people prefer over standard oral supplements. The exact rate of transdermal absorption is still under study, but the effects of sea salt on muscle tension and skin health are well documented. The mineral-rich environment offers a way to support the body's internal balance without synthetic additives.
🧘 Comprehensive Physical Advantages
The physical act of swimming or floating in the sea provides a range of health benefits that work together to improve overall vitality. These advantages come from the combination of water pressure, mineral content, and the coastal environment. Notable benefits include better skin barrier function and hydration from the high saline content, improved mood from inhaling negative ions generated by crashing waves, reduced inflammation and muscle pain from the buoyancy of saltwater, and stimulation of the lymphatic system, which aids natural detoxification.
💡 Embracing Blue Mind Science
Integrating regular ocean visits into a wellness routine can lead to long-term improvements in how the body handles daily stressors. By providing mineral therapy and nervous system grounding at once, the sea acts as a wellness center that is available to everyone. The approach emphasizes environmental connection in maintaining internal harmony. It encourages a shift away from synthetic solutions and back toward the elements that have supported human life for centuries 🐚.

The ocean offers both mental and physical health benefits through its mineral-rich water, coastal air, and soothing environment.
Physical Benefits
  • Mineral Absorption: Seawater contains high levels of magnesium, potassium, calcium, and sodium. Magnesium is absorbed through the skin, helping relax muscles, support cellular energy, and aid nerve function. 
  • Skin Health: Salt water acts as a natural exfoliant, clears excess oils, and magnesium-rich seawater can help soothe skin roughness and inflammation. 
  • Low-Impact Movement: The buoyancy of salt water reduces stress on joints, making swimming, walking, and paddleboarding easier ways to build cardiovascular strength.
  • Airways and Breathing: Coastal air carries fine mineral particles and sea mist that can help keep upper airways moist. Breaking waves release negative ions that promote relaxation and clear breathing.
Mental Benefits
  • Stress Reduction: Simply sitting or swimming by the sea lowers cortisol levels, slows the heart rate, and shifts the nervous system out of "fight-or-flight" mode.
  • "Soft Fascination": The rhythmic sound of waves and expansive ocean horizons allow the brain to rest from mental fatigue, a concept explored in coastal wellness and National Geographic research.
  • Mood Enhancement: Time spent near blue spaces helps trigger positive brain waves and reduces symptoms of anxiety and depression.

  • Community Perspectives

Opinions differ on the direct medicinal effects of seawater. While many view the ocean as a natural restorative, some users on Quora note that while salt water can help clean minor surface scabs, open wounds exposed to ocean bacteria can sometimes take longer to heal.

The San Francisco 49ers Lose Their First Game of the Season

A painful lesson in American football: A halftime lead does not guarantee victory

Today, October 25, 2026, was a disappointing Sunday for me as a football fan. The San Francisco 49ers, one of my favorite NFL teams, lost to the Atlanta Falcons by a score of 29–20.

What made this defeat particularly disappointing was that the 49ers were leading at halftime. They started the game well, but the Falcons gradually took control and eventually handed San Francisco its first loss of the season. Until today, the 49ers had won all six of their games.

As I watched the game, I was reminded of an important lesson in sports and perhaps in life: It is not how you start that matters most, but how you finish.

How the Game Unfolded

The 49ers started strongly. Running back Christian McCaffrey scored the team's first touchdown, and backup running back Kaelon Black added another with a 30-yard run. San Francisco built a 14–3 lead in the second quarter.

However, Atlanta fought back. The Falcons scored a touchdown and a field goal before halftime, narrowing the 49ers' lead to just two points. The halftime score was San Francisco 14, Atlanta 12.

The second half was a different story. Atlanta quarterback Michael Penix Jr. threw touchdown passes to Kyle Pitts and Drake London, helping the Falcons take control. Penix threw three touchdown passes during the game.

The 49ers tried to rally in the fourth quarter. Quarterback Brock Purdy connected with fullback Kyle Juszczyk for a touchdown, bringing San Francisco within six points. Unfortunately, the 49ers missed the extra-point kick.

San Francisco still had opportunities to recover, but costly mistakes hurt its chances. Purdy threw two interceptions, and the 49ers lost possession of the ball on fumbles. Atlanta took advantage of these mistakes and added a field goal to secure its 29–20 victory.

The result was a surprise. The undefeated 49ers had suffered their first defeat of the season, while the Falcons earned an important home victory.

A Simple Explanation of American Football Scoring

Some of my worldwide readers may not be familiar with American football. Unlike soccer, where each goal normally counts as one point, American football awards different numbers of points for different plays.

Here are the basic rules:

  • Touchdown — 6 points: A player carries the ball into the opponent's end zone or catches a pass there.

  • Extra point — 1 point: After a touchdown, the team usually kicks the ball through the goalposts.

  • Two-point conversion — 2 points: Instead of kicking, a team can try to carry or pass the ball into the end zone again.

  • Field goal — 3 points: If a team cannot score a touchdown, it may kick the ball through the goalposts during a play.

For example, a touchdown followed by a successful extra-point kick earns seven points. That is why football scores often look quite different from soccer scores.

A game consists of four quarters, each lasting 15 minutes of playing time in the NFL. The clock frequently stops, so a game usually takes considerably longer than one hour to watch.

Teams also have limited opportunities to advance the ball. The offense generally has four downs, or attempts, to gain at least 10 yards. If it gains those 10 yards, it earns another set of four downs. If it fails, it usually must give the ball to the opposing team.

This makes every possession important. A fumble or an intercepted pass can change the direction of a game in a matter of seconds.

What Went Wrong for the 49ers?

In my opinion, the most important factor was the number of costly turnovers. The 49ers gave the ball away four times, including two interceptions and lost fumbles. The Falcons converted these mistakes into valuable scoring opportunities.

Football is a team sport. A good offense can score many points, but the team must also protect the ball and play effective defense.

The 49ers had opportunities to win, but Atlanta made the important plays when they mattered most. The Falcons deserve credit for their victory.

There is also a concern about injuries. McCaffrey, one of San Francisco's most important offensive players, left the game temporarily with a thigh injury. His condition will be worth watching as the season continues.

My Thoughts as a Football Fan Nearing 92

At my age, I have learned not to expect every day to go according to plan. The same is true of football.

A team can dominate early and lose its advantage. A player can make a brilliant play and then make a costly mistake. Sometimes, a small detail, such as a missed kick or an intercepted pass, can determine the outcome.

I have followed sports for many years, and I still enjoy the excitement and uncertainty of watching a close game. That is part of what makes sports entertaining. We can make predictions, but we cannot know the outcome until the game is over.

I will continue cheering for the San Francisco 49ers. One defeat does not erase the team's six victories or determine what will happen during the rest of the season.

For my readers who follow soccer, basketball, cricket, or other sports, the lesson is familiar: a lead is never completely safe until the contest is finished.

And for those who do not follow American football, I hope this short explanation has made the game a little easier to understand.

Win or lose, there is always another game to watch, another lesson to learn, and another Sunday to enjoy.

At nearly 92, I am grateful that I can still follow the games, share my thoughts with readers around the world, and enjoy the simple pleasures of life.

Go, 49ers! I hope you come back stronger in your next game.

I Mailed My Ballot: Should We Ask Artificial Intelligence Who to Vote For?

Yesterday, I mailed my ballot.  At my age, approaching 92, I no longer drive. Mailing my ballot is not simply a matter of convenience. It is a necessity that allows me to continue exercising one of my most important rights as an American citizen: the right to vote.

I live at The Heritage Downtown, a senior living community in Walnut Creek, California. Although I live alone, I am not lonely. I continue to play bridge, write my blogs, follow the news, and take an interest in what is happening in our country and around the world.

Growing older may limit some of our physical activities, but it should not mean giving up our voice in the affairs of our nation.

Today, however, two news stories caught my attention. One concerned the growing number of Americans who have already voted in the upcoming November 2026 elections. The other, reported in the news, concerned Americans turning to artificial intelligence, or AI, for help in deciding which candidates deserve their votes.

The second story made me stop and think.

How Does Voting Work in America?

For my readers outside the United States, let me briefly explain the American electoral process.

The United States is a representative democracy. Citizens who are eligible to vote choose people to represent them in government. Depending on the election, they may vote for a president, members of Congress, state officials, local leaders, judges, or other positions. They may also vote on specific proposals called ballot measures.

The United States has elections at several levels of government. Federal elections concern the national government, state elections concern individual states, and local elections may determine who governs a city, county, or school district.

In November 2026, Americans will participate in the midterm elections. These elections take place halfway through a president's four-year term. Voters will elect all 435 members of the House of Representatives and approximately one-third of the United States Senate, along with many state and local officials.

Unlike countries where elections are conducted through a single national system, American elections are administered largely by individual states and local election officials. Rules concerning voter registration, identification, mail ballots, and deadlines can therefore differ from one state to another.

There are several ways Americans can vote.

Some go to a polling place on Election Day. Others vote in person before Election Day through a process called early voting. Many voters, including senior citizens like me, use mail-in ballots.

A mail-in ballot allows an eligible voter to receive a ballot, mark the choices privately, and return it according to the state's rules. Depending on the state, it may be returned through the postal service, placed in an authorized ballot drop box, or delivered to an election office.

For people who no longer drive, have mobility difficulties, or cannot easily stand in line, voting by mail can make participation in democracy much more accessible.

I mailed my ballot yesterday because I want my voice to be heard, even though I can no longer drive myself to a polling place.

Millions of Americans Are Voting Early

News reports this week described millions of Americans already casting their ballots before Election Day.

According to a report published on October 21, approximately 14.3 million Americans had voted in the 2026 general election at that point. About 9.1 million had voted by mail and 5.2 million had voted in person before Election Day.

These figures are an early snapshot, not the final national total. They show that Americans do not all wait until Election Day to exercise their voting rights.

For me, the important point is not which candidate or political party receives the most votes. It is that citizens have an opportunity to participate in deciding the future of their country.

Democracy depends not only on the people who run for public office but also on ordinary citizens who take the time to vote.

When Artificial Intelligence Enters the Voting Booth

The other news story surprised me even more.

Some Americans are asking AI chatbots to help them decide whom to vote for. They may ask a chatbot to compare candidates, explain their positions on important issues, examine their professional backgrounds, or even recommend which candidate they should support.

A Pew Research Center survey published on October 23, 2026, offers some useful perspective. Among American adults surveyed, 8 percent said they were using AI chatbots for information related to the 2026 elections.

Among those using AI for election information, many wanted to learn where candidates stood on issues or check the accuracy of claims they had heard. Forty percent of this group said they had used chatbots for suggestions about how to make their voting choices.

These findings suggest that AI is becoming another source of election information, although most Americans are not yet using it for that purpose.

I can understand why people might turn to AI. American ballots can be complicated. A voter may face several candidates for different offices, each presenting promises and arguments. There may also be ballot measures written in language that is difficult to understand.

AI can explain unfamiliar terms, summarize a candidate's stated policies, and help compare different positions. Used carefully, it can help citizens become better informed.

But there is an important difference between asking AI to explain the choices and asking AI to make the choice for us.

I Ask AI to Help Me Write, Not to Decide My Vote

I have been using AI to help me write my blogs for readers around the world.

I write about my experiences growing up in the Philippines, my years as a pharmaceutical chemist, my late wife Macrine, my Catholic faith, aging, science, and the many changes I have witnessed during my lifetime.

Sometimes I ask AI to explain a scientific discovery in simpler language. At other times, I ask it to help organize my thoughts or make an article easier for readers whose first language is not English.

I find this particularly useful because my readers come from many countries and backgrounds. I want them to understand my stories without having to struggle with complicated English.

Nevertheless, the experiences and opinions expressed in my blogs are mine. AI can help me communicate them, but it cannot replace the memories, values, and personal reflections that make them my own.

The same principle applies to voting.

I would ask AI to explain a candidate's position, but I would not ask AI to tell me whom to vote for.  Why?

Because voting is not merely a mathematical exercise in which a computer compares several names and announces a winner. It is a personal decision involving our values, our experiences, our hopes for the future, and our understanding of the responsibilities of government.

Two intelligent people can examine the same facts and reach different conclusions. One may place greater importance on the economy, another on health care, and another on education, immigration, the environment, or the country's international responsibilities.

There is no reason to assume that an AI chatbot understands an individual's priorities better than that individual does.

Can We Trust Artificial Intelligence?

As a retired pharmaceutical chemist who spent many years working with scientific information, I have learned to distinguish between a claim and the evidence supporting it.

AI is an impressive technology, but it is not infallible.

It can provide outdated information, misunderstand a question, overlook important details, or present an incorrect statement in convincing language. Its responses can also be influenced by the information available to it and the way a question is framed.

Political information presents particular challenges. Candidates may change their positions, campaign advertisements may contain misleading claims, and different sources may describe the same event in different ways.

An AI-generated summary may sound balanced without necessarily giving equal attention to all the facts that matter.

Therefore, anyone using AI to research an election should check its claims against reliable sources, including official election websites, candidate statements, reputable news organizations, and independent fact-checking services.

AI can help us find and understand information. It should not become our only source of information.

And we should be especially cautious when a chatbot gives us the answer we already want to hear. Agreement can be comforting, but it is not proof that we are correct.

The Ballot Is Mine, and the Responsibility Is Mine

As I approach my 92nd birthday, I have lived through many political changes, technological advances, and international events.

I have seen the world change from an era when information traveled slowly to one in which a person can ask a computer a question and receive an answer within seconds.

This is progress, and I welcome many of its benefits.

Yet some responsibilities should remain firmly in human hands.

My ballot represents my judgment as a citizen. I may seek information from newspapers, television, conversations with other people, official documents, and even artificial intelligence. But after considering the available evidence, the final decision belongs to me.

I do not expect every reader to agree with my approach. Some may find AI useful in narrowing their choices. Others may prefer to study the candidates entirely on their own.

What matters is that we remain thoughtful, independent, and willing to examine the evidence before making a decision.

In a democracy, we should not surrender our judgment simply because a machine can produce an answer quickly.

Yesterday, I mailed my ballot. I did so because I still believe that my voice matters, even at nearly 92.

I may need a cane to walk, help with some computer tasks, and the assistance of my children for certain errands. But I can still think, reflect, and make my own decisions.

That is a privilege I do not take for granted.

A Final Reflection

Technology can help us write our stories, understand complicated subjects, and communicate with people across the world. It can also help us become better-informed voters.

But technology should assist our judgment, not replace it.

I will continue asking AI to help me write about the world I have experienced and the lessons I have learned. When it comes to voting, however, I believe the responsibility must remain my own.

My ballot carries my name, my conscience, and my responsibility as a citizen. No machine should cast my judgment for me.

At nearly 92, I have learned that growing older does not mean surrendering the right to think for ourselves.

And perhaps that is one of the most important lessons we can pass on to the next generation.

Until my next blog, may we use the gifts of technology wisely, preserve our independence of thought, and never forget the value of a single human voice.

AI Impressions and Notes on this Topic: 

This is an excellent subject for your David At Nearing 92 blog. Your personal experience of mailing your ballot gives the article a human touch, while the question of asking artificial intelligence for voting advice raises an important issue for our time: AI can help us understand the world, but should it decide how we vote?

For your worldwide readers, I have explain the American voting process in simple language, compare your use of AI for blogging with using AI to choose candidates, and emphasize the importance of personal judgment and civic responsibility.

Editorial note: I have treated the early-voting figures as a dated snapshot, rather than a final count. The published figures I found for October 21 were approximately 9.1 million mail ballots and 5.2 million early in-person votes.

When 10,000 Minds Work for 88 Hours: What AI Just Did to Mathematics

Abstract flow of mathematics - turbulence and light representing Navier-Stokes
THE MATHEMATICS OF FLOW

When 10,000 Minds Work for 88 Hours: What AI Just Did to Mathematics

October 24, 2026By David B. Katague, Walnut Creek, CAFor worldwide readers of chateaudumer.blogspot.com

I am writing this from my small desk here in Walnut Creek, at 91 nearing 92 years young, with the morning light coming through the window. For more than six decades I have watched mathematics move at the pace of a human life,  one blackboard at a time, one letter, one proof, one quiet doubt. Last week, something happened that makes me sit back and simply breathe in wonder.

In October of this year, an announcement came that I never imagined I would read in my lifetime. I want to share it with you not as a technical expert, but as an old man who still believes that wonder is the most important thing we can pass on.

1. What happened

According to OpenAI, over a single long weekend -88 hours, they set loose not one AI, but 10,000 AI agents working together. Not chatting, not writing poems, but doing mathematics. Real mathematics. The kind that has kept the best minds awake for a century.

Their target was one of the seven Millennium Problems set by the Clay Mathematics Institute in the year 2000 - the Navier- Stokes existence and smoothness problem. It is a question about water, air, and flow itself: can we prove that the equations that describe fluid motion will always remain smooth and well-behaved, never breaking into nonsense?

The system did not just produce one draft. It produced 722 complete manuscripts, touching 372 distinct families of problems, lemmas, counter-examples, extensions, and bridges I am still trying to understand. Within that forest of work sits what they claim is a full proof of Navier-Stokes. The Clay Institute has not yet finished its long review as it should not, these things must take years  but even the claim, with the weight of checking behind it, has shaken the world of mathematics.

Think of it: 10,000 minds that do not sleep, do not eat, do not forget what the 9,999 others have just discovered, working for 88 hours. That is roughly 880,000 hours of concentrated thought compressed into less than four days.

2. The human story

When I first read this, I thought of my professors in the 1950s, smoking pipes, erasing a blackboard for an hour to get one line right. I thought of my classmates who spent an entire summer on a single inequality.

Some will say this is the end of the human mathematician. I do not believe it for a moment.

What I see is not a replacement but a mirror. For the first time, we can see what mathematics looks like when memory is perfect and stamina is infinite. It shows us how much of our work was limited not by our intelligence, but by our time by the need to sleep, to raise children, to grow old. The young mathematician in Nairobi or in Mindanao who has an idea at 2 a.m. can now ask 10,000 tireless colleagues to test it with her.

The proof, if it holds, still had to be asked for by a human. The question was human. The courage to declare one of the Millennium Problems solved that, too, is human. Machines can produce manuscripts; only we can feel the trembling of the hands when we read them.

3. What remains for us

At 91 nearing 92, I have learned that the important questions are rarely "Can we?" but "What now shall we do?"

First, humility. We must wait. A proof is not true because it is large, or because it is produced quickly. It is true because it survives the patient, sometimes cranky, careful reading of other human beings. That review will take years, and that is good.

Second, gratitude. If you have ever stared at a flowing creek and wondered why it curls the way it does, mathematics is trying to honor your wonder. Whether it is proved by a man with chalk or by 10,000 agents humming in a data center, the beauty belongs to all of us.

Third, invitation. There is more room now, not less, for the human voice. We need explainers, doubters, poets of logic, teachers who can take these 722 manuscripts and tell our grandchildren what they mean. At my age, that is the work I love most  sitting with you, dear reader from wherever you are reading, and saying: Look what we humans have dreamed up to do.

The sea is still out there beyond the Chateau. It still flows by rules we are just beginning to name.
