Eat Red Meat and Die ….. NOT NOW! ….. Maybe, sometime.

June 19, 2019

Here we go again.

“Eating even the moderate amounts of red and processed meat sanctioned by government guidelines increases the likelihood of developing bowel cancer” according to the above article in The Guardian, UK.

The sample size was 500,000. That’s good. It is a self-selecting sample. That’s not good. They could all be health fanatics. But here is the kicker:

“The researchers found those who ate the most and least red and processed meat tended to exaggerate their consumption or lack thereof.”

That’s a shock. People lie or exaggerate. Even the researchers then suggest – despite the screaming headline – that you don’t change your diet.

Although, looking at the plate above … I would!

Real Men Eat Red Meat and Die … Sometime!

Eat Meat and die??????

According to this headline in THE AUSTRALIAN 25th, March 2009   meat eaters are at risk of dying of cancer. The study published in  Archives of Internal Medicine involved half a million people over 10 years. So far so good. That is a good sample size. The sample consisted of people aged 50 to 71 years at baseline or, obviously, after 10 years 60 to 81years!!!!  So some deaths would be expected. Nevertheless, the article states: 

“Men whose red meat intake put them in the top 20 percent consumption band were 22 percent more likely to die of cancer in the 10 years of the study, compared to men whose intake was in the lowest 20 percent. For women, there was a 20 percent increase in risk.”

Here is the problem. Firstly and I quote from the original study: “Meat intake was estimated from a food frequency questionnaire administered at baseline.’ So they asked people once what their eating habits were then assumed they continued for the next 10 YEARS??? How likely are your eating habits to change in 10 years???

Secondly, and this was mentioned in the article without explaining the maths, big meat eaters tend also to be big drinkers, smokers, obese and the rest. This study has tried to separate out meat eating from other unhealthy lifestyle choices using the Cox Regression. Mathematical wizardry has produced these numbers but they don’t mean much. 

If the study used a control group of drinking, smoking, obese vegans then compared mortality rates over 10 years that would be interesting. But where do you find half a million of them???????? 

Finally,  the study  concluded ‘Red and processed meat intakes were associated with modest increases in total mortality, cancer mortality, and cardiovascular disease mortality.’ Not the stuff of headlines at all!!!!!!!

Cars in the USA are how old? Really? No way! Look at the World and Do the Math

February 3, 2018

 

The average age of the 60 years of FORD vehicles here is 30 years. MODEL NAMES at end of post.

I did this to show that averages can tell us a lot or, in this case, not very much.

Here are some averages that tell us a lot about different countries and their love of cars!

The average age of vehicles in USA is a record-high of 11.6 years. More here.

Car ownership rates data here.

This is the average vehicle age, which includes vans and utes. Almost 1,000,00 vehicles were scrapped in 2015-16. More than 30% of vehicles are less than five years old. Data here.

In 2016, the average age of vehicles on Canadian roads was 9.66 years. Data here.

The average age of cars in UK is 7.7 yrs. some interesting stats here.

The average age of vehicles in New Zealand is 14.3 years. The average age of trucks and buses is over 17 years. Data here.

Cars in the European Union are on average 10.7 years old. Data here.

The average age of vehicles in Poland is 17.2 years. Daata here.

The average age of vehicles in Romania is 15.3 years. Data here.

The average age of vehicles in Greece is 13.5 years. Data here.

Ethiopia has the lowest car ownership in the world with 2 per 1,000 inhabitants in 2014.

The average age of Ethiopia’s fleet is 15-20 years. Best guess! Data here.

2. Readability Algorithm

November 25, 2015

The above algorithms are called pseudocode because you do not type a letter to a computer to tell it what to do. You have to write code to instruct it.
But computer code, as my little sailor friend would say, uses a shipload of maths.
I am going to give you instructions by writing a letter to you because that is your CODE that you understand.
You are going to calculate the The Flesch–Kincaid reading score for The Hunger Games and a Harry Potter TEXT.
Don’t run screaming out the door. This is not too complicated.
The Flesch–Kincaid reading score or, quaintly, the F–K formula (Oops! Only one – )tells you the grade reading level of a text.
F-K formula
4. Flesch Kincaid Formula
We will use a basic version and a calculator:
5 F-K Formula Basic
You will need:
Word Count =
Sentence Count =
Syllable count =
The Flesch Reading Ease score is interpreted as follows:

6. Flesch Kinaid Readability Table

More info here.

READABILITY is important for Newspapers, books and websites

Text to be read by the general public should aim for a grade level of around 60 – 69 or Grade 8.
YA authors use the F-K formula to see if the text of their novel has the appropriate reading age.
YOU CAN TEST YOUR OWN WRITING! What reading age is your writing?

………………………………………………

 Are your FINANCIAL and LEGAL CONTRACTS READABLE?

You may be able to SUE your BANK!!!!!!!!!

Contracts, by law in the US, should be written to a reading score of Grade 8. According to a recent article in the Telegraph, UK:
Insurance and banking customers who have been mis-sold financial products are more likely to be awarded compensation if they use a scientific test to prove policy documents were too difficult to read.
The “Flesch Kincaid” reading score is well established in the US, where most states require insurers’ policy documents to be written at no higher than a ninth-grade level (14–15 years of age) of reading difficulty.

The New Age of Guess-amatics!

Mathspig pill bottle Hellooooo Sweeties,………………………………………………………………………

Some frightening maths this week. When researching DANGEROUS MATHS, Mathspig found one branch of maths is the most dangerous maths of all. Let’s call it GUESS-AMATICS. Today, maths is often taught via computer program packages. Some of these computer packages turn maths into a guessing game.

1 plus 1

This exact and rather frightening scenario was described to me by the mother of a 5 year old. The mother decided it was time to turn the game off. When students play mathematical computer games too often they don’t have to think, they just guess the answer and try again. But be warned this ‘Oops! Try again’ maths can kill you’! Some maths you cannot ‘try again’. You HAVE to get it right the first time. Medication is one area where ‘Oops! Try again maths kills”

Do the Maths and Do NO HARM.

You need sufficient maths to understand medication doses or you might do yourself harm.…………………………………………………………………………………..

And here is just one very frightening statistic:……………………………………..

According to FDA data 1.3 million people in the USA are injured each year from medication errors. Mathspig First Aid Saves

Meanwhile, we need nurses, caregivers, doctors, paramedics, First Aide volunteers, parents, grandparents, babysitters, teachers and all health care professionals to have sufficient maths to be able to calculate simple medication doses. Or we need them to simply READ the dose and make sure it is correct. Unfortunately, many of those who should be able to work out medication doses are either incapable or not paying attention. And your life could be in their hands:

UK

In the UK 1 in 20 hospital deaths is due to medical error. Nearly 12,000 patients die needlessly in hospital every year due to blunders by staff, researchers warn. Drugs or fluid mismanagement  was identified as a problem in 21% of preventable deaths (NHS   2012) or, doing the maths, 21% of 12,000 is approx 2,500 deaths due to bad maths! Mathspig Do meds do maths

USA

According to a new study just out from the prestigious Journal of Patient Safety, four times as many people die from preventable medical errors than we thought, as many as 440,000 a year. Mathspig Do meds do maths

Canada

Reports show between 9,000 and 24,000 hospital deaths due to medical error. Mathspig Do meds do maths

Australia

Official Australian government reports reveal that preventable medical error in hospitals is responsible for 11% of all deaths in Australia or 1 in 9 deaths.

Dangerous Maths 1:Young drunk dead

Mathspig Dangerous Maths

Statistics for alcohol consumption are tricky. Binge drinking gets confused with heavy drinking. If you want to stay young go to the UK. They think anyone under 35 is a youth! Some stats separate Male and Female drinking habits. Some don’t. And legal drinking ages vary. Canada is one crazy place. It has different legal drinking ages in different parts of the country.

  1. 15-24 years average 1990-2002 Source
  1. Under 18 years of age. 1996 It is believed that as many as 83 percent of teenagers in Canada consume alcohol. Back in 1996, underage drinking was responsible for 3,500 deaths and 2,000,000 injuries. A 2002 survey found that 20 percent of eight graders had consumed alcohol within the previous month. Source
  1. 4,358 people under age 21 die each year from alcohol-related car crashes, homicides, suicides, alcohol poisoning, and other injuries such as falls, burns, and drowning. Source

Mathspig 9 Youth alcohol related deaths These countries have different populations (See post below). USA population is 15 times Australia’s. 260 x 15 = 3,900. So the Aussie and US stats are in the same ball park even though the stats have been collected for different age ranges. But look at Canada. The USA population is about 9 times Canada’s. 4,358 ÷ 9 = 484 deaths. This  death statistic for Canada is 10 times larger than the USA statistic per head of population. Meanwhile, the population of Canada is 1 1/2 or 1.5 times Australia’s. 260 x 1.5 = 390. Once again, the Canadian statistic is out by a factor of 10. What’s going on here?

How to pig out and save the planet

January 2, 2015

Aussie physicist and TV present – that does sound like an oxymoron – Reuben Meerman (A meer man after all. Old joke) had an article published in the BJM (British Medical Journal) with Andrew Brown describing where fat goes when you lose it.

When you burn fat which is a triglyceride or a three-pronged hydrocarbon the formula is:

Picture 1

You breath out the FAT as CO2 and H2O.

BUT:

Oxidizing 10 kilos of human fat requires inhaling 29 kilos of oxygen to produce 28 kilos of carbon dioxide and 11 kilos of water. You can check out how much carbon dioxide you add to the atmosphere when you diet in the following graph:

Picture 3

Mathspig Kilo carbon dioxide released per kg FAT

 Picture 3

When you lose weight you add carbon dioxide to the atmosphere, but when you gain weight you take carbon dioxide out of the air. Your carbon footprint from Time for Change blog (See table below) can be neutralised if you put on the following weight:
