From sugar makes you fat to vaccination beliefs

Well, does sugar really make you fat? This is perhaps too generic of an argument. A much better argument is that eating too many calories for the amount of exercise or movement you do. Sugar on my cereal each day might make me fat but might have no effect on my children.

Could I convince you that sugar is bad if I had a study? Would the author of the study matter? How about where the funding came from – a sugar company or a non-governmental organization on general nutrition?

I feel that “to vaccinate” vs “not to vaccinate” falls into a he said she said type of argument. It is very complex dealing with preservatives and stabilizers and has a lot of finger pointing.

Vaccines as well as foods also contain some substances for preservation. These preservatives help both foods and medicines to have a shelf life of more than a few days. This is one of those things that have helped us move from a society of hunters and gatherers living from day to day to a society that does not need to produce and use these items immediately.

Some of these preservatives, well for foods anyway, are reasonably familiar.

  • Salt
  • Nitrates
  • Sulfates
  • Sodium Benzoate, Potassium Benzoate and Benzene (ok, not so familiar)

A lot of Anti-vaxxers are concerned when they see things like Thimerosal which is a type of mercury as a preservative in vaccines. I get it, mercury is bad for you.

Con argument

Mercury? It is know to be harmful for the nervous, digestive and immune systems, lungs and kidneys, skin, eyes and gastrointestinal tract … need I go on?

Pro argument

Well, you wouldn’t want micro organisms living and growing in the medical juice we will be putting into your arm. It would undermine the entire reason for doing so.

Its complicated

The issue is actually more nuanced that this but what does tend to be the case is that you see very educated people on both sides of the argument. This should not be too surprising. In many different situations there are people on both sides of an argument.

The good or bad news is that both sides bring their own studies into the argument and this is where things can get a bit problematic. If there is a supporting study that suggests having a certain medicine has a terrible side effect then is the argument finished? Did one side win?

Maybe. Having a study is good news as it shows why we should change our behavior but only if it was a good study. A good study should contain a lot of of the folllowing attributes.

  • Uses statistically large enough sample size
  • Clearly states the variables or constructs to be examined
  • Performed in a systematic way
  • It is based on some logical rationale and tied to theory
  • Provide data and methods
  • It can be replicated

Based on a lot of information I have seen about aluminium, sugar, transfats, … it is not usually possible to know if any of these or all of these attributes are being used. In many of cases, the studies seem to be done by the the group who wants to prove the result.

How to decide?

Well, the most important attribute from that list is “can it be replicated”. This is usually clarified by the term “peer reviewed” or replicated by an group of independent researchers.

Anyone can have an opinion and the opinions of a doctor, lawyer, or television star is no more important than your opinion. An opinion supported by studies and research is good but an opinion supported by independent studies and proven by others in the field is much much better.

If something cannot be “scientifically proven”, then perhaps this is less a scientific argument and more an argument of faith. Nothing wrong with that, but lets keep in perspective.

The Upgrade

A couple of years ago my wife bought a HP pavillion gaming notebook. It has an Intel I7 with 16 gigabytes of ram and a one terabyte hard drive. Despite having windows 10 as the operating system it has been a great notebook. Everything has been just fine for gaming and photo editing but lately she has been complaining that her program cannot open up images to be edited. Well, it turned out that she was having space problems. It turned out that the windows partition was on its own 128gb m.2 drive which was full, and not a little full but virtually completely full with about 1 gigabyte free.

First attempted rescue

Back in the good ol’days the solution would be to get a larger disk drive and to clone the old disk onto the new disk. I downloaded clonezilla which would have been a great help. You had to be careful of which drive or partitions needed to be copied but the entire process could easily be done in a couple of hours.

I didn’t think the situation through and so I tried to fix my problem just like the olden days – well it didn’t work. I received a windows error and a blue screen. Despite all my efforts I was not able to boot the newly imaged drive with the old partitions.

I did some further investigating on the internet and came up with a second possible solution.

Second attempt

The good news is that I am not dealing with a dead hard disk. Microsoft actually created a backup tool to create a system image of the entire computer. This is really cool for a computer that has just been recently setup, even better when the computer has a single drive with a single partition. Some of the videos I saw on the internet suggested you can select which partitions can be backed up using Microsoft’s system image backup.

The notebook still worked fine so it was just a matter of backing up the operating system image and restoring it to a new hard disk.

However, as simple as this process sounds has a lot of steps a casual user wouldn’t feel comfortable doing.

I think having a SSD as the operating system disk makes for a really fast pc but it boggles the mind how most non-technical people deal with this type of partition full issue. My wife, initially couldn’t believe she had about 900MB free but her computer was “full”.

She is very hands on person but the video describes how to take the entire bottom off of the laptop. Not only is taking the bottom off your laptop too much for most people in this case it also involves tools that a lot of people don’t own. Consumer friendly laptops have a small door to access memory or hard disks or other laptops while others, such as the XMG Apex 15, have a easy to remove bottom.

Upgrades are not necessarily a technical challenge but between how most laptops are built and the process of installing or migrating Windows is too much for most people.

Voted off the island

I was frankly happy when the US presidential election was over. It was a long tiring process that took forever and once it was over it still wasn’t really over. Cries of “fake news” and “election fraud” were scary initially until they appeared to be just political posturing – well in the worst possible way.

The election is really over, and the ex-President is now long gone. I was surprised to see a bit of news about one of the Fox News reporters. It seems that the veteran politics editor Chris Stirewalt was fired.

This could be a coincidence and that Fox News simply decided after the election they needed fewer staff now that the election is over? What is unique about Chris is that he, along with Bill Sammon, were involved in making the decision to call the Arizona election in favor of Joe Biden over Donald Trump. They called the state of Arizona but they also did this before all other news networks did. I guess you could even say that they scooped the other networks.

In the end it turns out that this was indeed the correct call but with Fox News calling the state for Biden I suspect they received a lot of negative feelings and feedback from both their viewers and the ex-President.

It is sad that someone who reported the facts should loose their job when others on the same network promote that there was fraud in the 2020 election but still retain their job.

Excessive shaming, cover your ass or follow the leader

Just recently we have seen a rather unprecedented suspension of use by a number of public platforms for President Trump, now ex-President Trump.

  • Twitter
  • Youtube
  • Facebook
  • Instagram
  • Snapchat
  • Reddit
  • Twitch
  • Liquid Web
  • Shopify
  • stripe
  • paypal

A lot of these were social media sites but this list also includes some payment services. It is possible that these were suspended to prevent any further encouragement of the rioters. An impartial view of the of the ex-President’s inability to tweet out his important thoughts might be a good preventative measure but is it censorship? Well, I guess using the textbook definition it is certainly censorship. Does this prevent him from communicating and reaching his political base?

Well, I suppose that is complicated. As the president of the United States, now former president, he commands the ability to simply hold a speech and the reporters from the various large news organizations come running. So it is definately possible for him to communicate with anyone willing to listen. It is my personal opinion that ex-president Trump liked to communicate via Twitter due to the control he was able to exert.

You do not have to like him, his style or his politics to see he knows how to resonate with a crowd. He is very good at controlling his image and Twitter was perfect. He could say what he wanted and he didn’t have to face down a room of reporters who might ask difficult questions. Worse still those reporters would then have either audio or video of any answers which can be used at any point to tarnish his image.

Beyond censorship

There are probably as many different opinions as people on should you be able to turn off the leader of a country’s microphone. Whether or not you agree this is an acceptable method you might wonder about some of the other different organizations who are now shunning ex-President Trump.

It is difficult to know when to cut bait in any situation. I think the most generous person in the world might be able to look at some of the things Trump had said in the media or on social media and suggest this was beyond poor taste. Yet, like anything in life, once you start to acquiesce in a situation you become more and more invested. The more invested the hard to stop any given activity.

The recent protest, riot or attempted coup probably seemed like a convenient spot for most organizations to terminate their relationship. Once a few organizations terminated their relationship it was easier for everyone else to jump on the anti-Trump train.

Much in the way that President Trump has been maintaining his image over the decades he is now victim of other organizations doing the exact same thing – maintaining their images. His polarizing ways and his alleged connection with the activities on January 6th are exactly the things that in my opinion would have gotten most other people banned from most social media platforms. It is actually just easier for most of these organizations to use the fine print in their contracts to get rid someone who could be a brand problem in the future.

Free Market

It was probably harsh realization to the ex-President but there is another example from the news that supports a companies free will decisions. That court case went all the way to the supreme court which agreed that the bakery was not required to make a wedding cake for same sex couple. Companies, just like people, don’t have to do business with people they if they don’t want to.

It is impossible to know the exact reasons why these companies have broken their ties but it is a free market decision.

You don’t have to like ex-President Trump to know that things will be much much harder for him. It is quite likely with all of these organizations abandoning ex-President Turmp he could see a negative financial impact on his fortune.

https://www.forbes.com/sites/danalexander/2020/10/16/donald-trump-has-at-least-1-billion-in-debt-more-than-twice-the-amount-he-suggested/?sh=5106e6784330

The only thing that seems somewhat obvious is that if the market knows that ex-President Trump is in a bad financial situation that some of the financial sharks will be circling and waiting for the best time to make a deal – which will probably be the worst time for ex-President Trump.

Free markets and free will are great when everything is going your way but nothing lasts forever.

Name brand recognition or coincidence

When you work or live outside of the USA you sometimes want to have a taste for the familiar. It is actually surprising just how many products that have a big footprint in the US have little or no market presence in other countries.

It has been ages since I wanted a peanut and jelly sandwich but I do like to have peanut butter from time to time on my bread. Because peanut’s are not native to Europe a lot of peanut based foods are also not so common here.

I don’t have a favorite local brand as they keep changing at my local supermarket. I bought some a while back and I didn’t think anything about it until my wife surprised me with an actual US peanut butter.

It was then I notice the similarity. I do not think that most people in Europe know anything about Jif peanut butter but I was surprised to see my local peanut butter looking similar to a familiar brand.

The dirty business of politics in the 21st century

I don’t know how old you need to be to have heart the following saying.

damned if you do and damned if you don’t

Of course this phrase has the dictionary definition of an unwinnable situation. I have been watching the drama play out in Washington DC and it is difficult to know what the actual politicians think. I see news clips or bloggers talking about how in private the politicians are saying there was no fraud in the presidential election but nothing on the record.

I do rather wonder if this is partly because those politicians or vice president are in an unwinnable situation but one with rather serious consequences.

It is one thing to be the unpopular kid on the play ground who has the fear a bully might take away your lunch money or generally harass you. Can you imagine in what position the politicians are in. They know that there is a republican base of approximately 74 million people who seem to be supporting President Trump in all he does. Just a week ago, a pretty small group of those supporters took their beliefs quite a bit farther and occupied the capital. The group that went all the way and broke into the capital appear to be more hard core than most. They must be in order to travel from their home, most of which were outside of DC, just to attend this event and create this chaos.

Now imagine that some of these people live in your home district or somewhere in your state. I can only imagine that one reason the politicians are so quiet about their Trump opinions is that they can imagine a lifetime of having a flaming bag of poop on their door step, cars scratched in a parking lot or worse.

I think that all politicians on both sides of the aisle have this in their mind but what about vice President Mike Pence. Before January 6th, he had pretty much two choices.

  • Preside over electoral vote counting in ceremonial role
  • Somehow try and overturn the election in favor of Donald Trump

With these two choices he must have felt like he somehow won the worst job in the world – quite literally.

His current boss is not at all understanding of anyone who does not fulfill his requests. If Mike Pence fails to overturn the last possible opportunity overturn the election the chance his boss would show some understanding was slim. He might be fed to the “not so understanding” Trump base creating problems with disgruntled voters for years to come. The net result could be those flaming poop bags or toilet paper on Halloween at the minimum. If he looks behind door number two and somehow overturns the election, he will also be vilified by the non-Trump base, have the opportunity for toilet paper and such on Halloween. Door number two doesn’t seem any better but it gets worse.

If he had tried to fool with the electoral vote process, it would have eventually been overturned by the Supreme Court and go down in history as a traitor to democracy.

damned if you do and damned if you don’t

All of this hassle for this ceremonial vote counting. Is it any wonder that he did not choose to take up the congress request for him to implement the 25th amendment of removing Trump from office. He has been thrown under the bus while he was with his family in the capital building. He was probably concerned that “… even worse” might happen to him from the Trump supporters if he had removed the President even a few days early.

I think it is possible to not respect the vice president at all and still feel a small bit sorry for him. Not for his politics as he has pretty much determined his own future but that the constituents in this political game are taking this too far.

Covid 19 problems real or imagined

I received a email about death. I am not going to post the entire email but it was related to the death of a generally healthy doctor in Florida a few weeks after taking a covid 19 vaccine. The facts of this is as follows:

  • died 15 days after first injection of vaccine
  • Death of thrombocytopenia(ITP) which is a lack of platelets
  • Light drinker (on social occasions)
  • Non-smoker
  • generally fit who did outdoor activities

According to my email, ITP autoimmune condition, is the third most common problem after getting an influenza vaccination. It is always sad when someone dies before their time has come which is why Covid 19 is such depressing disease. It has been the straw that has been breaking the back of many people who have other health condition. Sure, eventually they would have also succumbed but this might have been years or decades later.

Was this death the result of a vaccine? It is difficult to say but we can say that as of the writing of this blog, Jan 12, 2021, approximately 29 million doses have been administered and there does not seem to be any other people who have had this reaction.

This could indeed just be a rare autoimmune reaction or latest disease caused by something else. The numbers that came up during my research were perhaps a few thousand cases a year for ITP. The human body is pretty complex, there are also a number of other autoimmune diseases that occur that have not yet been blamed on Covid 19.

  • Type 1 diabetes
  • Rheumatoid arthritis
  • Multiple sclerosis
  • Systemic Lupis
  • Inflammatory bowel disease
  • Graves disease
  • Celiac disease

I was not aware that these more common diseases are actually autoimmune diseases and between all of them they cover millions of unhappy people each year.

Fun fact. People with celiac disease cannot eat foods that contain gluten. Gluten is a protein found in wheat, rye and other grains. It is because of this disease that it is possible to find so many gluten free products in the supermarket.

It is also possible to anaphylactic shock when getting a vaccine or some injection which also can be quite serious but can be brought about by a number of different external factors succh as insect bites, foods, medications, latex exposure or exercise. It is also possible to have an anaphylactic shock for no reason whatsoever.

Yup, all of this actually sounds similar to something my father once said. If you give a can of (your favorite soft drink) to one million people someone will probably die. Indeed, nobody wants to die from something as mundane as a vaccination but some of the Covid 19 alternatives are worse.

  • Permanent heart damage
  • Permanent lung damage to the air sacs in lungs
  • Strokes or seizures
  • chronic fatigue
  • Guillain-Barre syndrome
  • Blood clots and blood vessel problems
  • death

I guess all of this focuses around your risk horizon. If you think that big pharma will kill you you can roll the dice and see how you fare with Covid 19.

I am not a medical physician so none of this is advice but I am going to give the vaccine a chance. The second worst thing that can happen is a mutation that give me X-Men powers.

Stay healthy.

The crux with drugs

In the intervening months I have actually read quite a few emails about trust. Rather than bore you with a complete list here is a few of the more common issues of trust.

Don’t trust

  • .. the media
  • .. masks
  • .. the <fill in the blank> political group they are socialists or fascists
  • .. the election, it is rigged
  • .. <fill in the blank> government official they have an agenda

I especially like the list item on that list. If there is a voter or citizen who does not already realize your politician has an agenda you may need to readjust your thinking a small bit. Yet, today I am more interested in medication and not just those little blue pills.

Big pharma

Pharmacutical companies are not non-profit nor are they just for the betterment of mankind. There have been in recent times stories of how some companies are taking their medical patents and using them to legally to take medications which used to cost dollars to increasing the prices so they cost hundreds or thousands of dollars.

https://www.forbes.com/sites/matthewherper/2017/02/10/a-6000-price-hike-should-give-drug-companies-a-disgusting-sense-of-deja-vu/?sh=317c910971f5

h ttps://www.nytimes.com/2015/09/21/business/a-huge-overnight-increase-in-a-drugs-price-raises-protests.html

We can see with this brief look they are no angels. It has been raised by some people on the internet that the new Covid 19 vaccine is not just new but done using a completely new technology one that uses mRNA. One of the questions is this an effective vaccine? Well, who knows but that isn’t as important as the second question will there be any unknown safety issues in the future because of it. Before considering this we might consider the rest of the world around us.

Energy

Fracking is a new way of extracting energy from the ground. We have no idea of the long term effects of this new method of injecting water and chemicals into the rock to extract the locked energy. There could be safety issues with either the method or the chemicals used.

https://en.wikipedia.org/wiki/List_of_additives_for_hydraulic_fracturing

https://www.wilderness.org/articles/article/truth-about-fracking-and-environment#

This is not the only energy issue. There have been other environmental problems due to the oil industry. Why is this important? It really isn’t unless you want clean water for drinking or to be used in the processing of food.

Agriculture

Back in the day the big boy on the block was big tobacco. They were selling a product that was intended to be lit on fire and inhaled. This product was accused to causing cancer, heart disease, strokes, and lung disease just to name a few. The industry did the only thing they could which was to downplay these issues. Eventually, in the US, they did come to a massive settlement with 46 US states and 5 territories. It seems likely that there was some merit to this case and that this product was not the healthy choice and but yet the companies fought to continue for decades.

https://www.publichealthlawcenter.org/topics/commercial-tobacco-control/commercial-tobacco-control-litigation/master-settlement-agreement

Products

Construction and manufacturing are not necessarily innocent either. A few decades ago it was decided that Asbestos should not be used due to the health side effects related to this product. In 1991 Asbestos was banned in the US in a majority of products. However, the knowledge that this was a problem since the 1940’s didn’t prevent them from continuing to use it as long as they could – well even use it today in some consumer goods but in lessor amounts.

https://www.asbestos.com/products/consumer/

https://www.mesotheliomahelp.org/asbestos/history/

Asbestos did spawn quite a few lawsuits but one of which awarded Judith Winkel 13 million against Colgate-Palmolive. It seemed that her talcum powder was contaminated with Asbestos.

Food

I have never run a company which prepares food for resale. I can only imagine how much paperwork and rules that need to be followed. However, despite this there are numerous cases of food being recalled every year. I just picked one for 2020. It seems that this food had hard plastic included with it which is why it was recalled.

https://www.globenewswire.com/news-release/2020/08/01/2071442/0/en/FSIS-ISSUES-PUBLIC-HEALTH-ALERT-FOR-MEAT-AND-POULTRY-TAQUITOS-AND-CHIMICHANGAS-CONTAINING-FDA-REGULATED-DICED-GREEN-CHILIES-THAT-HAVE-BEEN-RECALLED-DUE-TO-POSSIBLE-FOREIGN-MATTER-C.html

I also remember in Germany a few years back there was a salmonella problem. It was not immediately known what was the source. If I remember correctly initially there was a tenative link between vegetables and the outbreak. This made salads pretty much non-existant until the source was found. The cause was bean sprouts.

https://pubmed.ncbi.nlm.nih.gov/24434173/

Contaminating containers

This hit me personally when a few years back my wife started to throw away some of our plastic food storage containers. I did not need to read the entire article to know I did not want my mama’s chili to leach chemicals from the container into my food.

https://www.health.harvard.edu/staying-healthy/is-plastic-a-threat-to-your-health#:~:text=Studies%20have%20found%20that%20certain,including%20obesity)%20and%20reduced%20fertility.

Back to vaccines

What does all of this have to do with vaccines? Well these are things that we put into or onto our body. Every time a new vaccine is released conspiracy theory network publishes a lot of the same theories on how they will kill us. This time is no different, I saw this just the other day.

The vaccine is contaminated with aluminum, mercury, and possibly formaldehyde.

Well, no not really. Some vaccines contain Thiomersal which is a mercury compound but this not the dangerous methylmercury which tends to be found in fish. Besides if Thiomersal was a problem we would have been seeing the results as this has been used since the 1930’s as a preservative in biological and drug products.

https://www.fda.gov/vaccines-blood-biologics/safety-availability-biologics/thimerosal-and-vaccines

Without being pedantic about it, lets focus on those three substances once again.

  • Aluminum
  • mercury
  • formaldehyde

Yup, Aluminum. Aluminum is not actually very good for the body and yet you will find it used in many of the deodorants on the market. Well, it shouldn’t be a problem if I smear a small bit of it under my arm. Yeah, but it is also used in quite a few other every day items.

  • Antacids
  • dyes
  • cake mix
  • processed cheese
  • baking soda/baking powder
  • cosmetics
  • lotions

I didn’t receive any emails this morning talking about how I should throw away my aluminum baking tins due to increase of Alzheimers, epilepsy, dementia or ADD.

https://keeperofthehome.org/eliminating-aluminum-from-our-homes/

We do not have to take a flu (or covid 19) vaccine but the reason we do is because the the chances of problems for the average person are pretty low (a small number of people per million typically have serious problems). Lets look at the counter argument. Nobody takes the vaccine and let nature take it course.

Well, the hospitals will fill up with people who would not have gotten ill. We need to keep them separated from the rest of the patients in the hospital but due to how easily spread covid 19 is, the hospitals get fuller and fuller. The problem is that hospital capacity is not infinite and if there is no free beds then other patients cannot use them. These other patients might be because of stroke, heart attack, auto accident or even appendicitis. If there are not beds for these people it goes without saying that other less serious conditions that can usually be schedule also cannot go to the hospital.

Depending on high the numbers are, the hospital personal will essentially become a death panel. They will look at your condition and say go home and they will call if they have space.

Should we take the vaccine? This is a tough call if you have bad health, are easily susceptible for diseases or are quite allergic to some of the contents of the vaccine. Those people are safer when the disease is not running rampant. The disease doesn’t run rampant when we have heard immunity which can occur only in two cases.

  • lots of people get the disease, some dying[1]
  • lots of people get vaccinated and so do not spread the disease

You shouldn’t trust that “big pharma” has altruistic intentions. Those companies are filled with people and people can make mistakes. However, should you hold the vaccine to a higher standard than these other industries? All of them affect our daily lives. Should you choose to skip the vaccine, please be consistent and hold all companies whose product is ingested to the same standard.

I am looking at you fast food, sugar and general processed food industries.

No one complains about not getting a sunburn

If you have an email account you have probably received spam mail or a few jokes but lately the number of emails on healthcare and covid 19 have exploded. These emails range from informative to conspiratorial but there is one thing that these mails don’t ever mention.

Masks help. They should be thought of in same light of that 20th century personal protection equipment – sunblock. At the beaches and at the pools people use this miracle lotion to prevent the dreaded sunburn. Nobody, well nobody that I have ever spoken to has used suntan lotion and complained that they didn’t get sunburned.

We should remember this when “complaining” about wearing masks in corona times. We wear them with the hope that we never get sick. We should look at the bigger picture and remember the goal is to wear these uncomfortable things for a while and just grin and bear it.

Posted in corona times | Comments Off on No one complains about not getting a sunburn

PPE, Masks and Covid hands

I can only suppose that Personal Protection Equipment (PPE) was a think prior to Covid 19 but my head must have been somewhere else as I never heard of it.

Well, I hear about it now. It is on the news, periodically you even hear normal people talking about it. I hear it more than most people as my wife works in a hospital. During the early days she was unhappy at how many people would be hording personal protection equipment which made it difficult for the hospital to get enough for their staff.

She was also at times critical of bits of advise that was available for people via the internet. I have to be honest, it is possible that in the past I actually tuned her out – after all I wasn’t hording anything.

Well, it all came up the other day when I was finishing up on a home project. It involved some painting and because I didn’t want to get paint on my hands so I wore a pair of gloves.

After removing my gloves

Well, as I was cleaning my hands and complaining about it when my wife reminded me about failures of PPE. Masks and gloves do an amazing job of protecting you but only if you use them properly. Simply adding medical gloves does not necessarily make you safer. In my case paint provides a very visible reminder gloves do not provide magical protection.

If you are not careful of how you use gloves you might very well get Covid 19 or any other dirt or disease on your hands when removing them. Wearing medical gloves may just give you a unrealistic sense of security.

The best advise seems to be

  • wash your hands
  • social distance
  • wear a mask
