ICE (internal combustion engine) design wasn't based on this adulteration originally. They had to accommodate the design.

US government wanted to incentivise the corn growers. In the meantime, we have this propaganda about peak oil for 30 years. They didn't consider engineering innovation, using alternate fuel and electricity. Pushing more corn for motor fuel is an environmental disaster considering how much water is required to grow that corn with little fuel yield.

In recent years, it appears that the flex fuel fad is no longer strong. It is almost forgotten in many places. Very few cars can use that fuel. That is a good thing. The market force can simply reject a corrupt idea.

A new proposal would shrink the public’s right to comment on the rulebooks that govern grazing, logging, and permits across the national forests.

A New York judge on Monday sentenced Chinese billionaire and prominent critic of the country’s Communist Party Guo Wengui to 30 years in prison for financial fraud.

Interesting that China started planning this much earlier than the Western world expected.

Any number divided by 7 follows a recurring pattern after decimal. For example,

1/7 = 0.142857 (whole set recurring)

2/7 = 0.285714 (whole set recurring)

3/7 = 0.428571 (whole set recurring)

4/7 = 0.571428 (whole set recurring)

5/7 = 0.714285 (whole set recurring)

6/7 = 0.857142 (whole set recurring)

Also notice that the first digit after decimal increments to the next larger digit with every numerator increase.

Note: by recurring I mean this --

⅐ = 0.142857142857142857142857142857...

I learned this when I was young from my dad, decades ago. He passed away a few years ago. He was a professor.

Yet they are all but disappearing slowly from the US roads. Cars are planted on curves and turns. SUVs are like boats. I used to drive cars until started driving SUV a few years ago. Going to go back. Tired of boat driving.

This year, I bought one. I saw glorious reviews. It is expensive at $699 plus $99 pen. Runs Android 16 based Oxygen OS. My experience has been mixed to say it gently.

1. It is fast if you are doing web browsing.

2. Microsoft office apps get stuck opening or sharing anything.

3. Same story with Google office or productivity apps.

4. It is a big tablet for handling conveniently. But that is not the tablet's fault.

5. The screen quality is subpar even though it has a higher refresh rate.

6. Light sensitivity on screen brightness is inconsistent.

7. Many popular Android apps don't support tablets or don't support landscape mode. That is however not the tablet's fault.

8. Holding the tablet without a case is difficult. It is heavy and tends to slip out of hand.

9. The stylus is not helpful much. It is proprietary and has some navigation quarks. I don't really use it.

Generally speaking, apps getting stuck is the biggest problem in this expensive device. I can live with other features.

When I created this username, it was more like a casual idea. I don't particularly take life seriously. You got only one and there is no way to get out of it to another one.

Over time, I have seen that name does have an influence on reactions from people in a conversation. Some people outright told me that they didn't expect any serious response from me.

This app doesn't allow changing names per situation. It would be interesting to be able to change the handle by the participating sub to match the intent. However, it is not a big deal. I still like my username and it probably reflects my personality more accurately outside of my professional life.

Do you like your username or wish to change it? Why?

Summary:

For years, calcium and vitamin D supplements have been promoted as a simple way for older adults to protect their bones and prevent falls. But a massive review of nearly 154,000 people found that calcium, vitamin D, or a combination of both provided little to no meaningful protection against fractures or falls for most older adults.

​

Article:

​

A comprehensive review published in The BMJ suggests that calcium supplements, vitamin D supplements, or taking both together provide little to no clinically meaningful benefit in preventing fractures or falls for most older adults.

​

Falls are a major health concern among seniors. Nearly one in three people age 65 and older experiences a fall each year, and many of these incidents result in fractures. Such injuries can lead to pain, reduced independence, lower quality of life, and, in some cases, the need for long term residential care. As populations age, preventing falls and fractures remains an important public health goal worldwide.

​

Previous reviews have already raised questions about the effectiveness of calcium and vitamin D supplements. Research has generally found no reduction in fracture risk from either supplement alone, while results for taking both together have been mixed. The role of vitamin D in reducing falls has also remained uncertain.

​

Even so, vitamin D supplements (with or without calcium) continue to be widely recommended by healthcare providers, professional guidelines, and regulatory agencies for bone health. Prescriptions for these supplements have also risen considerably in recent years.

​

Analysis of 69 Clinical Trials

​

To better understand the evidence, researchers in Canada analyzed data from 69 randomized controlled trials involving 153,902 adults. The studies compared calcium supplements, vitamin D supplements, or a combination of both against placebo or no treatment to determine whether they reduced the risk of falls and fractures.

​

Although the quality of the trials varied, the researchers evaluated each study using established methods to assess both potential bias and the certainty of the evidence.

​

After establishing thresholds for what would qualify as a clinically meaningful benefit, the team found little to no reduction in overall fracture risk from calcium supplements (moderate certainty evidence from 11 trials; 9,067 participants), vitamin D supplements (high certainty evidence from 36 trials; 92,045 participants), or combined supplementation (high certainty evidence from 15 trials; 51,126 participants).

​

The analysis also showed little to no benefit for preventing specific fractures, including hip fractures, or for reducing falls. These findings were supported largely by moderate to high certainty evidence.

​

Findings Hold Across Different Groups

​

The researchers note that some parts of the analysis included relatively few studies and participants. As a result, the findings should be interpreted carefully. They also caution that the results may not apply to people with certain bone disorders or to those receiving medication for osteoporosis.

​

However, additional analyses produced similar results even after accounting for factors such as age, sex, previous fractures, previous falls, and average calcium intake from food. According to the researchers, this consistency strengthens confidence in the overall conclusions.

​

Based on the available evidence, the authors conclude that the findings "do not support routine supplementation with calcium or vitamin D, or combined supplementation to prevent fractures and falls."

​

They further suggest that clinicians, guideline panels, and regulatory agencies "should re-evaluate their general recommendations for calcium and vitamin D supplementation in light of current evidence."

​

Focus May Shift to Proven Fall Prevention Strategies

​

In a linked editorial, researchers say more rigorous and well powered clinical trials are needed to guide recommendations for people who may face a higher risk of fractures or falls.

​

Until then, they argue that resources and funding may be better directed toward strategies that have already demonstrated meaningful benefits. These include balance training, resistance exercise, and personalized fall prevention programs that combine approaches such as exercise, hazard assessment, and education based on an individual's specific risk factors.
