Short essays on a variety of topics including: health, Earth, healthcare, food, science, public health, education, and travel. Some videos too. Videos include film and movies. and, maybe, an occasional book review. There is an "Affirmations Page" in the left-hand column. This may be a place for some discussion of language,
"Aortic Valve Stenosis," at first look seems to be no diagnosis at all. However, when compared to a great many other diagnoses, an aortic valve stenosis seems more precise and useful than do many. It is an unhealthy narrowing of that valve opening. It says nothing about preventing it, curing it, or living with it. It does point out an unhealthy state.
Aortic, refers to the aorta. The aorta is an artery. A artery is a blood vessel which carries blood away from the heart an so carries oxygen and nutrients to the tissues of one's body. It is considered to be the main artery of the human body. It may be said to originate in the left ventricle of one's heart. A ventricle of the heart is one of the two large chambers toward the bottom of the heart. The ventricles collect and expel blood received from an atrium.Their are two atria in the human heart. The left atrium receives blood from the lungs.That blood has been oxygenated in the lungs.
The two atria are the smaller, upper, thin-walled chambers through which blood enters the ventricles.
There is a lot of somewhat unusual vocabulary used when the human circulatory system is spoken of. Pictures help. I need help doing pictures. There are lots of useful visual aids available online. Its mostly free. If you find something particularly good, please tells us about it in the "comments" widow below this post.
It looks to me like freshly oxygenated blood from the lungs arrives at the left atrium from largish vessels, one from each lung. From the left atrium, the blood passes through the mitral valve to the left ventricle. Blood from that left ventricle is moved though the aortic valve to the entire body, toes and brain.
The mitral valve is opened and closed through two flaps. It lies between the left atrium and left ventricle. As do all heart valves, it allows blood to flow in one direction only. A poorly functioning mitral valve can often lead to heart damage and death.
Back to stenosis of the aortic valve. An aortic valve which fails to fully close or open fully or not at all cause problems. If not at all the problem is short due to prompt death. For me the problem seems to be lack of oxygen reaching cells and then of nutrients not arriving too. Right now it feels as though even my heart is feeling that lack a lot. The more blockage the less life until no life at all.
So, the aortic valve controls the blood flow between the left ventricle and the aorta. Remember that the aorta is the large important artery through which blood with its oxygen an nutrients are delivered to the entire body from toes of feet to brain complete. The aortic valve controls this delivery and prevents back flow. If the valve stays closed one dies, brain, body, and all. If it stays open the heart heart fails and one dies, body, brain, and. When it stays partly open or closed one partly dies.
I have this in mind because I have recently been assured that aortic valve stenosis has been add to my spinal cord stenosis. It now seems my aortic stenosis is likely to kill me long before my spinal cord stenosis can do enough damage to kill me.
The following continues to be a bit about me. I am told that this process of narrowing of is common and probably not the first in me. I knew that because I have been diagnosed with what has been called a progressive spinal stenosis. And I have also been told that I have a sort of general atherosclerosis and arteriosclerosis and that is a sort of narrowing. And then I have been told that I have collapsed moribund capillaries in the brain and that is sort of extreme narrowing. And now I am reminded of being called narrow minded.
I am pretty sure that my aortic valve can realistically be called A key valve in my circulatory system. I have been privileged to see my valve failing to open and close fully in full motion black and white. And at the same time have seen the acumulations of calcium there that I have been told were showing up on my x-rays.
I have been experiencing lacks of energy these days with less recuperation. I am told that it is probably do to my diminished blood flow. That sounds reasonable. I now have to rest during showering and must take breaks during dressing. I awaken exhausted. I find more energy at times nearly every day. I can eat at the dinning room table, watch TV, and do this, but not all at the same time.
I had feelings and episodes that now suggest blood circulation problems. My more recent experience of fatigue, exhaustion, and lack of energy came on suddenly just before the pandemic. That appears to be belated to obstruction of flow at the valve. Awakening exhausted must be related to something.
So far I have been unable to consult a cardiologist, but believe I have and appointment for this month of January of 2022!
I continue to adjust my exercise program to my actual abilities.
Thanks for reading.

Some notes of mine from a book by Peter Elbow about learning to write without teachers I am rediscovering that he seems to be a very good teacher and writer. I am learning from these old notes. Maybe you can learn from them too. I intend to publish some posts dealing with them. This particular post is about editing one's writing.
RCS Posts Science including: phenomena, inference, observation, and method
Science is the practice of a method of understanding and of communication. It may be called the scientific method. This method can be a great help in self-development and in being a successful human being.
As you become better acquainted with this method of understanding you become a more effective person. You will also develop a better understanding of the sciences in general and of each individual science, even ytterbiumology.
The scientific method generally includes the following doings: observation, identification/recognition, description, experimental investigation, and theoretical explanation of natural phenomena. So, a scientist observes a doing or happening and begins to explain it. The method is much about how she does this. That is, how you do it may be more important than what you do.
To start well, lets try to define some of our terms. We can begin with the word 'science.' Starting at the beginning we see that science means knowledge, the business of knowing. Just how one knows is a serious subject. A subject we could check into later. Early in its history science became knowledge gained by study. Science brings its history with it. It still means knowledge and it still means knowledge gained by study. The science quickly came to be the study of particular and specific subjects. In its more modern meaning it has come to mean the technical and mathematical study of a subject. However the basic method of doing science is both a simpler and more powerful attitude then one might suppose.
We already know that "method" means "the way how." So, science is a particular way of understanding, a particularly effective way of understanding. It may be useful to remember that the suffix -ology means study. So, anthropology is the study of human species, of humanity in most of its aspects. It has often been a comparative study of behavior, biology, societies. Whereas biology is the natural scientific study of life and of living organisms. It is one of the more nicely developed sciences. Cells and genes are now important factors in this study.
It is important that a person interested in science develop a good grasp on the nature of scientific: observation, identification, explanation, knowing, researching, and theoretical description. Also to develop their ability to recognize and observe natural phenomena is helpful to their use of scientific methodology.
To gain and to communicate scientific knowledge one needs to become familiar with its concepts and vocabulary. As interest is shown, I hope to write more on the topic. I believe that you already have an understanding of the scientific method as a way many have found useful for gaining practical, productive knowledge and of communicating that knowledge.
You probably already have the understanding that science is well begun and carried out with studied and practiced observation.
The ways of scientific observation are important to the development of knowledge. My dictionary says this about "to observe:" to notice, to perceive, to watch attentively, to make a scientific or systematic observation. "Systematic," that implies that there is a system to be learned. It seems that the way of a scientific doing is, at least, as the what.
Observation is the act of observing; that is the act of noting and recording of a phenomena, doing, or happening, perhaps with instruments. Observation might lead to developing a judgement or inference. What are the methods for developing a judgement or an inference!
"Identify" could be our next term to examine. If you would like me to continue some sort of exposition of science, please leave a comment to that effect in the "comment" window below.
Identifying a phenomena is, in large part, for the purpose of being able to recognize the phenomena yourself and to enable others to also recognize it. There is more to say about the recognize/identify part of of our scientific process, but I will leave it for another time.
Oh, yes. Ytterbiumology is beyond my present knowledge; still it can be studied, known, and used. Its a chemical element with the symbol Yb and atomic number of 70. I may not live long enough to get deeply into the study of this element. Perhaps you can tell us more about it.

~ It is good to begin with a recipe.
~ Herbs and spices are often potent and they are not always cheap. Use them sparingly, at first.
~ Experiment with one herb at a time and on yourself, before offering your creation to a friend.
~ Buy herbs,spices, condiments one at a time and try them one at a time.
~ Cut little (or big) slits in your roast. Put selected 'herbs' in those to cook.
~ Start with herbs mentioned most often here and elsewhere.
Bon appetit

RCS Posts: Health with acupuncture, cheaper and better and politics.
It the wonderfully effective practice of acupuncture were to become common in the United States, the cost of healthcare there would drop. That is, improved healthcare care could very well become more affordable. People in the US could pay less for improved healthcare and become more able to pay for that care.
Cheaper and better seems a good deal.
The profession of anesthesiology could suffer because of the ability of acupuncture, in very many cases, to handle pain more safely, effectively, and with less expense.
MDs (medical doctors), anesthesiologists, and many drug manufacturers form a group not interested in supporting the use of acupuncture. They have strong reasons for that lack of support, mostly economical reasons. The AMA (American Medical Association) has shown itself to be not interested in promoting acupuncture. Healthcare users are the ones to be interested in bringing it to their own countries, but have been slow to learn about it; slow to learn because there have been few teachers and little information available.
With these little essays on acupuncture, I hope to educate myself and others on the topic. For the good effective use of acupuncture we benefit from our understanding and that of professionals in the field.
With increased use of acupuncture the huge amount of drugs American MDs prescribe would probably be less. Fewer prescriptions could mean less profit for drug manufacturers and a saving for many of us. So, we may add drug manufacturers to the group of those not interested in supporting the use of acupuncture.
Drug manufacturers have been interested in politics. They have formed and use powerful lobbying organizations in Washington. Drug companies contribute large sums of money to selected kinds of research. They have invested little in acupuncture. It seems safe to say that drug manufacturers are unlikely to support a health system which is not founded on drugs.
So, an active part of the medical establishment establishment has acrually organized to resist the use of acupuncture in the US.
For the individual the use of acupuncture could mean significantly lower medical costs and better health. What can the individual do about the use of acupuncture and the better of our health care system? Something, but not much. However, individuals can do all that is necessary. Note the letter "s" i have affixed as the last letter in the word "individuals." Individuals know how to co-operate and can act together effectively. They can even join an organization.
Greater use of acupuncture leads to significantly lower medical costs and to healthier health care. Acupuncture is a safer way to handle pain than is the use of drugs.
There is more we can do, and more we can learn. We are many and can co-operate.
The French, Russians, and others have encountered resistance to the practice of acupuncture of acupuncture, but have overcome much of it and are learning more of the practice and have been benefiting from it since about 1960. Even the Chinese have experienced some resistance related to the social changes there in recent decades. However, now the Chinese are now benefiting nicely from their use of acupuncture. Their excellent training has been renewed and continued research supported. There is wide active co-operation practitioners of acupuncture and the practice of western style medicine in use in China. Nearly all of china is now benefiting from better healthcare and more affordable costs from that co-operation.
In the United States about 20% of the costs to individuals for many procedures to to the anesthesiologist and his monitoring equipment. Monitoring is important, but can be excellent at lower costs. As we learn more about acupuncture, its safety, the way it can shorten hospital stays, and its chances for reducing insurance fees, the more interesting it looks.
It seems to me that we have much to gain from the practice of and further research in our use of acupuncture and that we are not doing enough to avail ourselves of important benefits.
I have said that acupuncture reduces and stops much pain in ways safer than those now common to us. When we look into the wonderful ways it can supplement our present healthcare by successfully treating and healing many ailments in ways our present system has had little success, it seems to be an area of healthcare we must explore.
You can begin to do something now. You can co-operate, team-up, partner-up. You can check around for good information about acupuncture near you. You can begin to separate the nonsense from good sense available online. You can share with family and friends the information you have and about where you lack information. You can ask people, that you know are interested in health, about where you can get more information.
You could look around to see if there is a practitioner near you with a good reputation. You might speak with that professional and ask him about his training and what he can do for you and yours. Or you may even be able to discover an organization interest in acupuncture which you can access. You could ask them what they are doing and think over their answers. You could check-out my other posts on acupuncture.
There may not be much you can do on your own and you really don't have to do anything. Still I believe that you can find that which you can do. We can learn a lot. We can help others around us just by raising our own awareness of the practice of acupuncture.

We
tend to think of a scientist as one of our more creative individuals.
We seldom think of a scientist as anything like a wage slave. However,
the fact is he usually has to work for someone. She often has a boss. She
may be fired.
For example:
~
The institution can have values that do not coincide with those of the
scientist. A scientist may dislike certain tools or methods of an
employer.
He
may not like certain ways in which his employer communicates. The
culture of the employer help do her work, but may also tend to limit his
thinking and productivity.
~
In addition to her salary a scientist may receive funding those whose
main interests are very different from hers. Her interest may well be
her branch of science and perhaps in interesting new paradigms. There
main interest at a given time might be profit and control of ideas.
Money can help, but it may also work to limit thinking and creativity.
~
Really big ideas may be fenced in, or out, by really big institutions.
The scientist may learn to stay safely on the rails of an old science
and to void the danger of trying to understand new ideas or taking on
promising new work.
It is not always easy to keep a mind free. One may even begin to lose heart.
May your heart be strong.
