ANZAC Day the 25th April - the importance of remembering

ANZAC Day falls on the 25th of April each year and now commemorates the service of Australians in many military conflicts across the world. The date originates from the landing of Australian and New Zealand troops on the coast of the Gallipoli peninsula on the morning of 25 April 1915 - the peninsula was fiercely defended by Ottoman Turkish forces and ultimately cost the lives of over 8,000 Australian service members before they were evacuated at the end of 1915.

At this time of continuing conflict in Eastern Europe, in the Middle East and simmering civil conflicts in other regions, the "Ode" printed below continues to resonate.

"For the Fallen"  by Laurence Binyon, published 21 September 1914, the fourth stanza of the poem - 

They shall not grow old, as we that are left grow old:
Age shall not weary them, nor the years condemn.
At the going down of the sun and in the morning
We shall remember them.


Lest we forget.

Cosmetics and fitness exercise: the combination may not work

                                                                                                Shutterstock
 
Cosmetics and fitness training - do they belong together ? Apparently no. There is a certain common sense logic to it - having foundation on the skin while exercising prevents skin pores from opening and releasing sebum. Sebum is a waxy. oily substance produced by the sebaceous glands that protects the health of skin.

A research study from Texas A & M University - San Antonio using a cohort of 43 college students (20 men and 23 women) monitored pore size and sebum production after the use of a skin cleanser and then application of foundation in a single layer on the participants faces.  The participants then ran for 20 minutes on a treadmill after which skin measurements were taken and the level of sebum assessed. Perhaps not surprisingly, it was found that the size of skin pores increased in areas of skin where there was no foundation applied in comparison to where it had been applied. It was concluded that the foundation cosmetic restricted pores from "..naturally enlarging during exercise, prevcenting the release of sebum and sweat, which moisturises and cools the skin" [Journal of Cosmetic Dermatology].

This research is probably not earth shattering in any measure as similar findings have been found for film/television production make-up, large body ink tattooes and body paint which prevents the skin "from breathing". It does however provide a measure of actual evidence to support the perspective that natural appearance is best.

So be safe, be sweaty !

9,000 to 10,000 steps a day - does it really help with health ?

                                                       Shutterstock
Taking long walks amounting to 10,000 steps has long been cited in the media and in various health related publications as beneficial for reducing heart disease and improving general health, however the origin of this claim and the evidence behind it, has long been a mystery. One suggestion is that the source of this claim comes from a marketing campaign promoting pedometers - which seems very plausible. Specific evidence of the health benefits has been minimal.

One study has now been released by the University of Sydney and published in the British Journal of Sports Medicine. This study involved 72,000 participants with an average age of 61 whom wore a movement tracking accelerometer on their wrists for one week. Over an average of 7 years, these participants were tracked and adjusting for factors relating to illness and death (diet, smoking, other forms of exercise), the optimal number of steps per day for a health benefit were between 9,000 and 10,000. This number of steps was calculated to provide a 39 % lower risk of dying duirng the follow-up period (the 7 years) and a 21 % lower risk of a heart-related incident. Happy walking !

Easter 2024

                                                                                                Shutterstock
Easter, a time of year associated with the Easter bunny, chocolate Easter eggs and for the religious, ceremonies such as the Stations of the Cross representing the death of Jesus Christ or Easter Sunday services. For many people, the public holidays bring a much wanted long weekend period to rest, have a break, see family and friends or pursue interests which are often harder to fit into busy working weeks. In a much troubled world with extreme uncertainties, wherever you may be, happy Easter !

Price of coffee

Think $5.50 is too much for a flat white? Actually it’s too cheap, and our world-famous cafes are paying the price

Emma Felton, University of South Australia

Even in a stubborn cost-of-living crisis, it seems there’s one luxury most Australians won’t sacrifice – their daily cup of coffee.

Coffee sales have largely remained stable, even as financial pressures have bitten over the past few years.

So too have prices. Though many of us became upset when prices began to creep up last year, they’ve since largely settled in the range between $4.00 and $5.50 for a basic drink.

But this could soon have to change. By international standards, Australian coffee prices are low.

No one wants to pay more for essentials, least of all right now. But our independent cafes are struggling.

By not valuing coffee properly, we risk losing the internationally renowned coffee culture we’ve worked so hard to create, and the phenomenal quality of cup we enjoy.

Coffee is relatively cheap in Australia

Our recent survey of Australian capital cities found the average price of a small takeaway flat white at speciality venues is A$4.78.

But in some international capitals, it’s almost double this, even after adjusting for local purchasing power parity.

In London, a small flat white costs about A$6.96. Singapore, A$8.42. In Athens, as much as A$9.95.

The cafe business is getting harder

Over the past few decades, coffee prices haven’t kept pace with input costs. In the early 2000s, after wages, food costs, utilities and rent, many cafes earned healthy profit margins as high as 20%.

The most recent data from IBISWorld show that while Australian cafe net profits have recovered from a drop in 2020, at 7.6%, they remain much lower than the Australian average business profit margin of 13.3%.

For an independent owner operating a cafe with the average turnover of A$300,000, this would amount to a meagre A$22,800 annual net profit after all the bills are paid.

What goes into a cup?

Just looking at the cost of raw inputs – milk, beans, a cup and a lid – might make the margin seem lucrative. But they don’t paint the whole picture.

Over the past few years, renting the building, keeping the lights on and paying staff have all become much bigger factors in the equation for coffee shop owners, and many of these pressures aren’t easing.

1. Green coffee price

Increasingly subject to the effects of climate change, the baseline commodity price of green (unroasted) coffee is going up.

Arabica – the higher quality bean you’re most likely drinking at specialty cafes – is a more expensive raw product. Despite levelling off from post-pandemic highs, its price is still trending up. In 2018, it sold for US$2.93 per kilogram, which is projected to increase to US$4.38 dollars in 2025.

Robusta coffee is cheaper, and is the type typically used to make instant coffee. But serious drought in Vietnam has just pushed the price of robusta to an all-time high, putting pressure on the cost of coffee more broadly.

2. Milk prices

The price of fresh milk has risen by more than 20% over the past two years, and remains at a peak. This has put sustained cost pressure on the production of our most popular drink orders: cappuccinos and flat whites.

3. Wages and utilities

Over the past year, Australian wages have grown at their fastest rate since 2009, which is welcome news for cafe staff, but tough on operators in a sector with low margins.

Electricity prices remain elevated after significant inflation, but could begin to fall mid-year.

Specialty vs. commodity coffee: why price expectations create an industry divide

One of the key factors keeping prices low in Australia is consumer expectation.

For many people coffee is a fundamental part of everyday life, a marker of livability. Unlike wine or other alcohol, coffee is not considered a luxury or even a treat, where one might expect to pay a little more, or reduce consumption when times are economically tough. We anchor on familiar prices.

Because of this, it really hurts cafe owners to put their prices up. In touch with their customer base almost every day, they’re acutely aware of how much inflation can hurt.

But in Australia, a huge proportion of coffee companies are also passionate about creating a world-class product by only using “specialty coffee”. Ranked at least 80 on a quality scale, specialty beans cost significant more than commodity grade, but their production offers better working conditions for farmers and encourages more sustainable growing practices.

Although not commensurate with the wine industry, there are similarities. Single origin, high quality beans are often sourced from one farm and demand higher prices than commodity grade coffee, where cheaper sourced beans are often combined in a blend.

Running a specialty cafe can also mean roasting your own beans, which requires a big investment in expertise and equipment.

It’s an obvious example of doing the right thing by your suppliers and customers. But specialty cafes face much higher operating costs, and when they’re next to a commodity-grade competitor, customers are typically unwillingly to pay the difference.

Approach price rises with curiosity, not defensiveness

When cafe owners put up their prices, we often rush to accuse them of selfishness or profiteering. But they’re often just trying to survive.

Given the quality of our coffee and its global reputation, it shouldn’t surprise us if we’re soon asked to pay a little bit more for our daily brew.

If we are, we should afford the people who create one of our most important “third spaces” kindness and curiosity as to why. The Conversation
