Sabalenka’s forehand said to be faster that Alcaraz's but women use different balls

Tennis coaching guru Patrick Mouratoglou claimed on LinkedIn that based on Aryna Sabalenka’s performance at the recent US Open Tennis Championships her forehand is faster than that of both Carlos Alcaraz and Jannik Sinner. 

“Aryna Sabalenka’s average forehand speed during this US Open is faster than that of top men’s players,” said Mouratoglous.

It is in the news but he forgot one crucial difference in the equipment used. Here it is:

In professional tennis, both men and women use the same standard tennis balls in most major tournaments. However, there is one notable exception:

In the U.S. Open, women play with a slightly different ball than the men. Women use the regular-duty tennis ball, which has a thinner felt coating, while men use the extra-duty tennis ball, which has a thicker felt. Both balls have the same weight and size, but the thinner felt on the regular-duty ball makes it move faster through the air, providing slightly different playing characteristics. 

Outside of the U.S. Open, both men and women typically use the same type of extra-duty ball in most other tournaments, such as the Australian Open, French Open, and Wimbledon.

Sorry, but the ''expert' appears to have made a fatal mistake in his argument. 

I suspect, actually, that the women play with different balls in more tournaments than is publicised but it is kept quiet. I am happy for them to play with balls that travel faster as it makes their game more interesting.

Research indicates that in the other three Grand Slams—Australian Open, French Open, and Wimbledon—men and women use the same type of tennis balls. This difference at the US Open has been a point of discussion among players, with some female players, such as Iga Świątek, advocating for the use of the same balls for both men and women.

Video of woman being arrested in a public place for eating someone's cat

Here is the video on X. It is weird and painful to realise that this woman allegedly ate a domestic cat and apparently there are witnesses so it seems she ate the cat in a public place. Dare I ask: "Did she kill and cook the cat, or did she just kill the cat and eat it raw?"

Makes me puke to think about it. But is it true? Remarkably it seems that there is a claim from Republicans that Haitian migrants in Springfield, OH are killing and eating pets. This arrest might be linked to that story. These claims are it seems politically motivated to boost Trump's campaign because he is very much against immigrants. The woman above is I believe Allexis Telia Ferrell and the place is Canton, OH, about 200 miles from Springfield.

I have just written about Trump's incredibly poor decision-making to rant and rave about this viral social media story in the presidential debate when it is not based on hard fact [link to follow-up article]. A terrible decision by him and he has egg on his face.

On Monday, social media was flooded with posts from prominent conservative lawmakers and commentators claiming Haitian migrants in the town of Springfield, Ohio, were brutalizing and consuming local cats and ducks. - Rolling Stone

This woman was arrested for eating someone’s pet cat in Ohio. How does something like this happen? pic.twitter.com/5zaFcARrHv

If she did eat a cat she must have been high on drugs surely. No other way a person could do that unless they were mentally ill. Days later the information is that this is 'fake' news but the picture is not clear.

The police officer wanted the Humane Society to take the deceased cat away. A bit odd that. Surely the cat should have been kept as evidence and after a trial cremated. It looks like the police had no intention of charging the woman and taking the matter to trial. Perhaps the police don't believe the witnesses. Perhaps this supports the claims that this is all bogus political shenanigans.

Linked article: Haitians killing and eating pet cats in Ohio? True or false? This is an evolving and therefore somewhat fragmented story.

This is a quote from The Mirror:

During his first debate with Kamala Harris, former President Trump told the millions of viewers: "They're eating the dogs, the people that came in. They're eating the cats, they're eating the pets of the people that live there. And this is what is happening in this country and it is a shame."

On the issue as to whether the allegation that Haitian migrants are killing and eating pet dogs and cats, Viles Dorsainvil, president of Springfield's Haitian Community Help and Support Center, told NBC News: "It's just bigotry, discrimination and racism. There is a group of people who have been fabricating some news just to denigrate Haitians."

JD Vance has admitted that "It's possible, of course, that all of these rumours will turn out to be false."

Although Trump insisted that they were true and as mentioned on this page, the Springfield city manager's statement that "there have been no credible reports or specific claims of pets being harmed, injured, or abused by individuals within the immigrant community," means that it's unlikely that the claims are true. And as mentioned also on this page I have hinted before that there appears to be an agenda here based on racism. Although a proper investigation would help.

Laughter can speed up recovery from illness. Study of sick kids in an Israeli hospital.

Being an old man, I am always interested in ways to improve one's well-being and overall health. It's important in many respects. In fact it should be a vital objective of all people. We should all be concerned with it and that includes people who care for a domestic cat companion. If a cat owner is ill it's unlikely they'll be able to discharge their cat caring duties fully. It affects the cat negatively. We create the cat's environment in all senses. I am not saying that being happy is easy becomes sometimes it is not!

Clown entertains sick child at hospital which speeds up recovery

With this in mind, it's a known fact that laughter can speed up recovery from illness. A recent study supports the findings of other studies and real-life experiences. In this instance it concerned children patients at hospital. They were seriously ill with pneumonia.

The researchers used a team of specially trained medical clowns with painted faces and the skill to entertain. They found that when they entertained the patients they cut the time they needed to be on intravenous antibiotics.

The researchers followed 51 children aged between 2 and 18 who had been admitted to hospital with pneumonia at the Carmel Medical Centre in Israel.

One group received standard care while the other received the same care plus a 15 minute session with a medical clown twice a day in the first 48 hours after admission to hospital.

The researchers employed three medical clowns from The Dream Doctors Project who use various techniques to relax patients. They employed music, singing and 'guided imagination'. They encouraged the children to drink and eat by themselves again.

The researchers discovered that the group who were visited by a medical clown had an average stay in hospital of 43.5 hours compared with 70 hours for the children who were not visited by the clowns.

Also, the children visited by medical clowns needed only two days of intravenous biotics compared with the usual three days for the control group.

The lead author of the study is Dr. Karin Yaacoby-Bianu. The findings were presented at the European Respiratory Society Congress in Vienna.

Looking wider, laughter is indeed a contributor to speeding up recovery from illness. It cannot be a cure on its own normally but other scientific studies have suggested that laughter because several positive effects on health and well-being.

For example:

• It boosts the immune system. It's been shown to increase the production of antibodies and activate T-cells which are essential for a healthy immune response.
• Laughter lowers the levels of stress hormones such as cortisol. These can weaken the immune system and slowdown recovery.
• Laughter triggers the release of endorphins. These are the body's natural painkillers which make it easier to manage pain and discomfort.
• And further, laughter improves blood flow and cardiovascular function. These are essential for recovery and overall health.
• And finally, laughter can alleviate stress and depression thereby improving mental health which can be common during illness. A positive mental state can promote faster healing.

Laughter isn't a replacement for medical treatment but it can complemented and enhance recovery.

America's top 2 cat associations should be ashamed of the Peke-face Persian

Here is another infographic about the health problems associated with the Peke-face Persian which is bred to extreme to create an entirely unnatural facial appearance which leads to many serious health problems. More to follow! Here are three concerning the mouth, coat and eyes. I am on the attack against cat associations which refuse to amend their breed standards to prioritise health in breeds.

When these cat associations - The International Cat Association (TICA) and the Cat Fanciers' Association (CFA) insist on certain anatomical features such as a sheer, flat face and a super-long hair you get the kind of health problem referred to in the infographic.

Flat-faced Persian cat coat, eye and mouth problems. INFOGRAPHIC. by Michael Broad

It is just not right that these cat associations have been encouraging and supporting breeders to create these unhealthy cats through their breed standards which, in Germany, would be called 'torture breeding' and banned.

There are other breeds that are inherently unhealthy and which should not exist such as the breed made popular by Taylor Swift who is incredibly influential; the Scottish Fold. She should be ashamed too. She is looked up to but she has her flaws, one of which is promoting an unhealthy breed that is also banned in Germany. The breed should not exist.

More: Vet accuses Taylor Swift of not being a true cat lover.

Below is a picture of a champion Peke-face Persian cat on TICA's website. Behind that image there is pain and distress in many ultra-Persian cats. It is a false representation of the state of this breed. It is a con basically.

FULL ASSESSMENT showing that electric vehicles are better than petrol vehicles for the environment

Here is a FULL ASSESSMENT showing that electric vehicles are better than petrol vehicles for the environment. The environmental impact of electric vehicles (EVs) versus petrol vehicles (internal combustion engine vehicles, or ICEs) has been a subject of extensive analysis. To fully assess whether EVs are better for the environment, several factors need to be examined, including emissions during use, manufacturing processes, battery production, energy sources, and lifecycle environmental impact.

1. Emissions During Operation

• EVs:
  • EVs have zero tailpipe emissions. They do not emit carbon dioxide (CO2), nitrogen oxides (NOx), or particulate matter during use, which is a key environmental benefit.
  • However, the electricity used to charge EVs can vary in its environmental impact, depending on the energy mix of the grid. In regions where electricity comes primarily from renewable sources (solar, wind, hydro), the emissions during charging are minimal. But in areas where coal or other fossil fuels dominate the energy mix, the charging process does contribute to CO2 emissions.
• Petrol Vehicles:
  • Petrol vehicles emit significant CO2 and other harmful gases during use. For example, a typical gasoline car emits about 4.6 metric tons of CO2 per year, depending on fuel efficiency. This includes NOx and particulate matter, which contribute to air pollution and human health issues.

Key Takeaway: EVs have a clear advantage in terms of emissions during use, especially in regions with cleaner electricity grids. Even in areas with a fossil fuel-heavy energy mix, EVs often result in lower emissions due to the higher efficiency of electric motors compared to internal combustion engines.

2. Manufacturing and Battery Production

• EVs:
  • EV manufacturing, particularly battery production, is energy-intensive. Studies show that producing an EV, especially its lithium-ion battery, can result in higher emissions than manufacturing a petrol car.
  • For instance, manufacturing an EV battery can emit between 50-75% more CO2 than producing a gasoline car. This is due to the mining and processing of raw materials like lithium, cobalt, and nickel, which are used in batteries.
• Petrol Vehicles:
  • Manufacturing petrol vehicles also requires substantial energy, but their engines are generally less complex to produce compared to EV batteries. As a result, initial manufacturing emissions are lower.
• Improvement in Battery Technology:
  • The environmental cost of battery production is decreasing as technologies improve and cleaner energy is used in manufacturing processes. Recycling initiatives are also being developed to reuse materials from old batteries, reducing the need for raw material extraction.
  • For example, second-life applications for EV batteries in energy storage systems are gaining popularity.

Key Takeaway: While EV manufacturing, particularly battery production, has higher emissions upfront, these are often offset over the vehicle's lifetime through reduced operational emissions. As battery technology improves and recycling grows, this gap is expected to narrow further.

3. Energy Source for Charging

• The environmental advantage of EVs depends largely on the energy mix used to generate electricity.
• Regions with Cleaner Grids:
  • In countries like Norway, where the majority of electricity comes from hydropower, EVs have almost no associated CO2 emissions during operation.
• Regions with Fossil Fuel Grids:
  • In places where coal or natural gas is dominant (e.g., parts of China and India), the advantage of EVs is reduced, although they still tend to have lower emissions over their lifetime compared to petrol vehicles.
• Global Trends:
  • As more countries transition to renewable energy sources (solar, wind, hydro), the carbon footprint of charging EVs will decrease. Governments are also offering incentives to speed up this energy transition, which directly benefits the sustainability of EVs.

Key Takeaway: The environmental performance of EVs improves dramatically as the electricity grid becomes greener. In the long term, with global moves toward renewable energy, EVs are positioned to become even more environmentally friendly.

4. Lifecycle Analysis (LCA)

A full lifecycle analysis includes emissions from the extraction of raw materials, vehicle production, vehicle use, and end-of-life disposal.

• EVs:
  • Several studies show that, over their entire lifecycle, EVs tend to have lower total CO2 emissions compared to petrol vehicles. A study by the European Environment Agency (EEA) found that, even considering battery production, an EV emits about 17-30% less CO2 over its entire lifecycle than a comparable petrol vehicle.
  • As battery recycling and production processes improve, this figure is expected to increase.
• Petrol Vehicles:
  • Petrol vehicles have lower manufacturing emissions but much higher operational emissions. Over a vehicle’s typical lifespan, these higher emissions outweigh the manufacturing benefits.

Key Takeaway: EVs have a lower overall environmental impact over their lifecycle compared to petrol vehicles, especially as grid energy mixes become cleaner and battery recycling advances.

5. Resource Extraction and Environmental Impact

• EV Batteries:
  • The extraction of lithium, cobalt, and nickel for EV batteries has significant environmental and social implications. Mining activities can lead to habitat destruction, water use, and pollution. Moreover, cobalt mining in particular has been associated with unethical labor practices.
  • However, there are efforts to develop alternatives to these materials, such as solid-state batteries, and to improve mining practices to reduce their environmental and social costs.
• Oil Extraction:
  • The extraction, refining, and transportation of oil for petrol vehicles also has severe environmental impacts, including oil spills, habitat destruction, and significant emissions during refining and transportation.

Key Takeaway: Both EVs and petrol vehicles are associated with environmental harm related to resource extraction. However, innovations in battery recycling and a move towards sustainable mining practices are improving the environmental impact of EVs, whereas oil extraction remains environmentally damaging.

6. Recycling and End-of-Life Disposal

• EVs:
  • EV battery recycling is still in its early stages, but progress is being made. Companies like Tesla and Redwood Materials are developing processes to recover valuable materials from old batteries, which can be reused in new ones.
  • This is crucial for reducing the need for new raw material extraction.
• Petrol Vehicles:
  • Petrol vehicles also have recyclable parts, but end-of-life disposal often results in waste, especially for non-metallic components like plastics.

Key Takeaway: EV recycling is improving and has significant potential to reduce the environmental impact of battery production, while recycling of petrol vehicles is more established but doesn’t address the fundamental emissions problem.

---

Conclusion

Based on the full assessment of available statistics and facts, electric vehicles are better for the environment than petrol vehicles, especially in regions with cleaner electricity grids. Key points include:

1. Lower operational emissions: EVs produce no tailpipe emissions and generally have lower lifetime CO2 emissions, even when accounting for electricity generation and battery production.
2. Lifecycle advantages: Despite the higher emissions from manufacturing, particularly related to battery production, EVs offer lower overall emissions over their lifespan due to zero emissions during operation and the shift towards renewable energy.
3. Battery technology advancements: Improvements in battery efficiency, production, and recycling are expected to make EVs even more environmentally friendly in the future.
4. Energy grid decarbonization: As more electricity grids shift to renewable energy sources, the environmental benefits of EVs will increase further.

While there are challenges related to raw material extraction and initial manufacturing, these are being mitigated by ongoing improvements in technology, making EVs a more sustainable long-term solution compared to petrol vehicles.
