Trump says some childhood vaccines will be split into separate shots
https://www.youtube.com/watch?v=VZZDSBxKvXo
I'm quite disappointed with Trump. This is an issue that has been very thoroughly studied.
Google AI:
There is no credible scientific evidence demonstrating that vaccines cause autism. Decades of rigorous global research involving millions of children have consistently shown no causal link or association between vaccination and autism spectrum disorders. [1, 2, 3]
The overwhelming scientific and medical consensus is supported by major global public health organizations, including the National Academy of Medicine, the Children's Hospital of Philadelphia, and the National Medical Association. [1, 2, 3]
The Origin of the Myth
The belief that vaccines cause autism stems from a single 1998 case series published by Andrew Wakefield in The Lancet. The study suggested a link between the Measles, Mumps, and Rubella (MMR) vaccine and autism based on just 12 cherry-picked children. It was later discovered that the data was fraudulent and methodologically invalid. The Lancet fully retracted the paper, and Wakefield lost his medical license. [1, 2, 3, 4]
Key Scientific Findings
Since then, numerous large-scale epidemiological and cohort studies have definitively debunked the link across three major areas of concern:
- The MMR Vaccine: Massive global studies tracking millions of children across the U.S., Denmark, the U.K., and Japan found absolutely no difference in autism rates between vaccinated and unvaccinated children. [1, 2]
Why the Misconception Persists
The primary driver of the myth is temporal coincidence. The first noticeable signs of autism typically manifest in toddlers around the exact same age that children receive their routine early childhood vaccinations. Because these two events happen around the same time, it can easily lead to the false assumption that one caused the other. [1, 2, 3]
The Actual Causes of Autism
Autism is a complex neurodevelopmental condition that begins well before birth. According to the Autism Science Foundation, the primary causes include: [1, 2]
- Genetics: Strong hereditary factors account for most cases, with single gene variants and familial risk playing massive roles.

This Woman Cured Her Cancer with an Insane Method
There have been reports of COVID-19 shrinking tumors, but not consistently. Reportedly, COVID-19 will attack every organ in the body.
The Disturbing Reality Of Ultra-Processed Food
I would like to see the research on whether ultra-processed foods are unhealthy. However, these foods often contain extra sugar and lack fiber.
Fiber is important for satiety. It makes us feel full by triggering a natural reflex in the digestive tract. Because of this, I have a theory that one might lose weight by starting meals with a high-fiber food, such as a salad, an apple, or beans.

How long does natural immunity last with COVID-19?
This came up in a recent conversation. Back in 2020, at least one person was saying 6 months. I'm at an age where I can get a booster every 6 months.
At the moment, just a simple cold has made me feel very bad.
It seems to me that natural immunity would last longer with repeated exposure. Doctors and hospital workers seem to be immune for long periods of time.
Natural immunity to COVID-19 typically lasts about 3 to 6 months against reinfection, though protection drops faster against newer variants.
UCLA Health
Duration of Protection
Against reinfection: Measurable antibody levels and protection against catching a mild or moderate infection start to fade after 3 to 6 months. Newer variants can bypass natural defenses more easily.
Gavi, the Vaccine Alliance
Against severe disease: Protection against severe illness, hospitalization, and death lasts much longer—often remaining strong for 10 months or more.
National Institutes of Health (NIH) | (.gov)
Factors That Affect Immunity
Variant changes: Mutations in the virus make it easier for reinfection to happen over time.
Severity of illness: People who had a severe COVID-19 infection sometimes build higher initial antibody levels than those with mild or asymptomatic cases.
BASS Medical Group
Hybrid Immunity
Getting vaccinated after recovering from a COVID-19 infection creates hybrid immunity. This combination provides a stronger, broader, and longer-lasting defense against current and future variants than natural infection alone. Health experts often suggest waiting 3 to 4 months after a natural infection before getting a booster shot.

Is Cottage Cheese Good for You? - Consumer Reports
https://www.consumerreports.org/health/nutrition-healthy-eating/is-cottage-cheese-good-for-you-a1956443640/
I've eaten cottage cheese since childhood. I don't even think of it as cheese because the texture is so different. However, large-curd cottage cheese has a texture I don't like, so I stick with small curd.
Cottage cheese is not one of my favorite foods because it is bland. Salt improves the flavor, and it becomes more interesting when you add fruit. I rarely buy it, though.
Most cheeses have flavors that don't appeal to me. However, I do like cheddar cheese. American cheese is essentially cheddar that has been highly diluted with other ingredients, such as oil. I think American cheese is only suitable for sandwiches.
I saw that one pizzeria said they put cheddar on their pizza. That's unusual, since mozzarella is the normal choice. I would like to try that.
Some pizzas are better without cheese. The cheese can hide the flavors of the other toppings. I've noticed that some places put the cheese over the toppings, while a few put the toppings over the cheese. I think the latter makes the pizza more flavorful.

Lindsay Clancy
https://en.wikipedia.org/wiki/Killing_of_the_Clancy_children
Conservative talk radio thinks that she should be found guilty.
One lady called into the Clay and Buck show and said that they don't understand psychosis. She said that she had wanted to kill her children, but got medical help and now takes antipsychotic medication. The lady said that she is afraid to stop taking her medication.
I find it easy to believe that people can go crazy. I already have that opinion about a few people. It appears that mental illness is fairly common.
I think that for a woman to kill her children is a crazy act by definition. There might be a few rare psychopaths who don't care and think that they can get away with the crime, but I doubt that they would try to kill themselves afterward. However, even psychopathy is a form of mental illness, although it is not the kind of crazy delusion where they don't know what they are doing.
Trying to kill oneself by simply jumping out of a second-story window is illogical, if not crazy, or it could be a carefully planned manipulation.

Is this trans thought experiment just wrong?
16 hours ago (edited)
A person's feelings about their body do not make a man a woman or a woman a man, nor is it possible to make the switch. A trans person will never be able to produce children. The changes are cosmetic only and don't change the fundamental reality of a person's biology. It seems to me that people are sold a lie about gender affirming care.
From what I read, some people do benefit psychologically from surgery. However, this is a serious operation that does irreversible damage to the body, with potential complications. Maybe psychological care would be more appropriate?
Some of us didn't exactly win the genetics lottery. We have to deal with the reality of our bodies instead of some fantasy. Surgery only becomes needed when it is medically necessary.

I used to eat salads, but I have been more nervous about lettuce lately. I have substituted chips and salsa. I find it very filling, which would make sense because it is high in fiber.

Why Fauci's Pardon Won't Protect Him From This
Rand Paul is using Fauci as a punching bag, trying to implicate Fauci for the pandemic, implying that it was created in a lab, to which Fauci provided a modest amount of funding to catalog bat viruses. However, none of this is supported by evidence, so this is just a witch hunt.
Many conservative commentators that I like regularly make statements about the pandemic that aren't supported by research. The truth is that masks and the vaccines slowed the spread of the disease. I have read the studies. The truth is that the vaccines reduced overall mortality at all ages.
Fauci deserves at least some credit for dealing with a major crisis under difficult circumstances. Instead, people want to condemn him over actions they find questionable. It is easy to second-guess people when you are not the one facing tremendous responsibility.

Caffeine and Adenosine Receptors
I quit caffeine a couple of different times by carefully measuring my intake and reducing it by a tiny amount every week. I was methodical about it, and my brain didn't notice the change from one week to the next.
That is currently my goal, but I'm in love with the boost I get in the morning from coffee. I quickly go from groggy to fully alert. Most Americans do the same thing.
When I wasn't consuming caffeine, just drinking liquid in the morning helped me get started.
Coffee is beneficial to health because of antioxidants, but we can get antioxidants from other sources.

I have concluded that a moderate amount of chips with salsa is healthy, and a good substitute for salads. The high fiber is filling and helps with appetite.
Tortilla chips are high in resistant starch, which is linked to some health benefits.
Google AI says...
Yes, lycopene is highly beneficial. It is a potent antioxidant found in red foods like tomatoes, watermelon, and pink grapefruit. It protects your cells from oxidative stress and is associated with a lower risk of heart disease, prostate cancer, and strokes. [1, 2, 3, 4, 5]
For maximum benefit, consider these key details:
- Better with fat: Lycopene is fat-soluble. Eating lycopene-rich foods with healthy fats (like cooking tomatoes in olive oil or eating them with avocado) boosts your body's absorption by up to 4.4 times. [1, 2, 3]
- Better when cooked: Heating and processing tomatoes (e.g., in tomato paste, sauce, or salsa) actually makes lycopene more bioavailable than eating them raw. [1]
Yes, salsa contains lycopene. Because tomatoes are the primary ingredient in traditional red salsa, the condiment is packed with this powerful antioxidant. Lycopene is linked to reduced inflammation, better heart health, and a lower risk of certain cancers. [1, 2, 3, 4]
The bioavailability of lycopene actually improves when tomatoes are cooked, processed, or mixed with a little fat (like avocado), making this flavorful condiment an excellent way to boost your daily nutrient intake. [1, 2, 3]
Yes, resistant starch is highly beneficial. It bypasses small intestine digestion, reaching the colon intact to feed beneficial gut bacteria. This produces short-chain fatty acids (like butyrate) that improve gut health, stabilize blood sugar, increase satiety, and support heart health. [1, 2, 3, 4, 5]
Key benefits of resistant starch include:
- Blood Sugar Control: Because it resists digestion, it does not cause blood sugar spikes. Some research indicates it can also increase insulin sensitivity. [1, 2]
- Gut Health & Digestion: It acts as a prebiotic, nourishing your microbiome and protecting the lining of the colon, which may lower the risk of colorectal cancer. [1, 2]
- Weight Management: By fueling the production of satiety hormones like GLP-1, it helps you feel full longer. [1]
You can naturally incorporate resistant starch into your diet by eating legumes, seeds, unripe (green) bananas, and whole grains. Additionally, cooking and subsequently cooling starchy carbohydrates (like rice, pasta, and potatoes) turns them into resistant starches. [1, 2]
Yes, corn tortillas contain resistant starch. The traditional process of making them—called nixtamalization, where corn is soaked in an alkaline lime solution—alters the starch and naturally increases resistant starch. [1, 2, 3]
You can boost the resistant starch content even further by cooking and cooling them (e.g., storing them in the fridge), which causes the starches to crystallize and become more resistant to digestion. For example, fresh corn tortillas might contain roughly 2.6 g of resistant starch, but this can increase to over 3.5 g after being chilled in the refrigerator. [1, 2, 3]

“You can and should continue to eat fruits and vegetables, but you might want to take additional precautions depending on where you live,” says James E. Rogers, PhD, director of food safety at Consumer Reports, who notes that so far, the majority of infections have been reported in Michigan, Ohio, West Virginia, Indiana, and Kentucky. “If you’re in one of those states, I recommend avoiding eating lettuce and salad greens until we know more, but currently, there is no data to support avoiding fruits and vegetables generally.”

Reducing the Risk From Arsenic in Rice
Our team tested three cooking methods ...
...adding rice to boiling water, cooking 5 minutes, and then draining the rice and cooking it in fresh water—known as the parboiling and absorption method..
...the parboiling and absorption method reduced the inorganic arsenic content in short- and long-grain brown and white rice by 50 and 58 percent, respectively. This could be a very effective strategy for families looking to reduce arsenic exposure while still eating rice. “In some cultures, people already prepare rice this way, and it appears to have a protective effect,”
Akinleye says. There is also data from other studies indicating that cooking rice like pasta and discarding the excess water can remove between 40 and 60 percent of the arsenic in rice, according to the FDA.
https://www.consumerreports.
Based on this, I think that the boil-in-the-bag method might be the easiest and still helpful.
I haven't cooked rice for years. However, I order Chinese food 2 to 4 times per month.
I own a small rice cooker that I haven't used.

I was drinking regular strength coffee, but I had a problem where my heart rate would stay high for hours. I substituted 50% decaf and did better.
Coffee is a diuretic. It definitely affects me. Like many people my age, I have to get up in the middle of the night to urinate. If I limit myself to one large cup of 50% decaf then I have a better chance of making it through the night.

Cancer Mystery Solved: Scientists Discover How Melanoma Becomes “Immortal”
Every time a healthy cell divides, its telomeres become slightly shorter. Scientists often compare telomeres to the plastic tips on shoelaces because they help protect chromosomes from fraying or breaking apart.
Eventually, telomeres shrink to a critical length, triggering a process called replicative senescence. At that point, the cell can no longer divide. This natural limit acts as one of the body’s important defenses against cancer.
Tumors must bypass that barrier to survive.
Many cancers accomplish this by reactivating telomerase, an enzyme that rebuilds telomeres and extends a cell’s lifespan. In melanoma, mutations in the TERT gene, which produces telomerase, are especially common. About 75% of melanoma tumors carry these mutations.
But there was a puzzle researchers could not explain.

As always, I would like to see more research.
Google AI says the following...
GlyNAC (a combination of Glycine and N-acetylcysteine) is highly beneficial as a strategy for healthy aging, specifically by boosting natural glutathione levels.
Research indicates that as people age, their ability to synthesize glutathione—the body's "master antioxidant"—declines. GlyNAC provides the necessary precursors to restore these levels, which in turn recharges cellular "batteries" (mitochondria) and combats oxidative stress.
Key Health Benefits
Clinical trials and research studies highlight several specific areas of improvement:
- Brain Health & Cognition: Supplementation has been shown to reverse age-associated cognitive decline and support overall brain health in both human and animal models.
- Physical Strength & Mobility: Older adults taking GlyNAC experienced significant improvements in muscle strength, gait speed, and exercise capacity.
- Metabolic Health: Studies found GlyNAC reduces insulin resistance and improves mitochondrial fuel oxidation, which is particularly beneficial for those with type 2 diabetes or metabolic dysfunction.
- Cellular Protection: It reduces chronic inflammation, oxidative stress, and genomic damage (DNA damage), which are key hallmarks of aging.
- Specific Conditions: Benefits have also been observed in patients with HIV, where it helped correct premature aging defects and improved quality of life.

The Disaster I Never Imagined Having To Worry About
https://www.youtube.com/watch?v=ksn5yrsC3Wg
I found this really interesting, but I assume that most people wouldn't want to watch the full 33 minute video.
The bottom line is that the AIDS drug Ritonavir started crystallizing during production making it not useful. This is because chemicals can take different arrangements called polymorphs. Once the process starts, it is impossible to stop because the crystals are self-replicating, and it is not simply a matter of cleaning or replacing all the equipment.
This process could affect many drugs we take. One researcher made it happen with aspirin.
This problem has led to increased medical regulation requiring research on possible polymorphs.

Massive biomolecular shifts occur in our 40s and 60s, Stanford Medicine researchers find
https://med.stanford.edu/news/all-news/2024/08/massive-biomolecular-shifts-occur-in-our-40s-and-60s--stanford-m.html
Scientific research suggests that aging is not a smooth, linear decline but rather a non-linear process characterized by "bursts" or "waves" of rapid molecular change.
Major Aging "Bursts"
Recent studies focusing on molecular and protein shifts in the blood and organs have identified several critical threshold ages where biological changes significantly accelerate:
- Age 44: The first major transition point. It involves shifts in molecules related to the metabolism of lipids, alcohol, and caffeine. Changes here are also linked to cardiovascular health and decline in skin and muscle integrity.
- Age 60: A second peak marked by dramatic shifts in immune regulation, carbohydrate metabolism, and kidney function. This corresponds with a sharp rise in the risk for age-related diseases like cardiovascular issues and Type 2 diabetes.
- Age 78: Earlier research also identified a significant shift around this age, specifically related to "old age" biological markers, though some recent studies had cohorts too young to confirm this specific peak.
| Age | Primary Biological Changes |
| ~44 Years | Lipid and alcohol metabolism; skin and muscle decline; cardiovascular markers. |
| ~60 Years | Immune system regulation; carbohydrate metabolism; kidney function; sharp rise in disease risk. |
| ~78 Years | Advanced proteomic changes typically associated with late-life biological aging. |
Scientific Insights
- Non-linear Nature: For decades, aging was viewed as a gradual accumulation of cellular damage. New "multi-omics" profiling shows that protein levels in the blood stay constant for long periods before undergoing "sudden upward or downward shifts".
- Organ-Specific Aging: Different parts of the body do not age in sync. For example, the aorta (heart) and blood vessels may show accelerated aging signals as early as age 50, followed later by the pancreas and spleen.
- Shared Between Sexes: While a peak in the mid-40s was initially thought to be linked to menopause, researchers found that men experience similar dramatic molecular shifts at the same age, suggesting deeper biological drivers beyond hormonal changes.
