Game one - in which my PSA has suddenly risen

One of the main killers of men is prostate cancer. When men of 'a certain age' get an annual blood test one indicator typically checked, along with cholesterol and so on, is our PSA (prostate specific antigen) value.

Many men have their prostate removed, so clearly one can do without it.

"Hey Google," I asked: "What's this prostate for anyway?"    
Her dulcet voice told me: "The prostate gland (the prostate) is an organ of the male reproductive system. It is about the size of a walnut and is found at the base of the bladder. The thin tube that allows urine and semen to pass out of the penis (the urethra) runs through the prostate gland. Alkaline fluid produced by the prostate gland helps to nourish sperm and leaves the urethra as ejaculate (semen)..."

Prostate cancer is the most common of these but can be slow in advancing so it is famously the one 'that most men die with, rather than die of'.  A PSA test provides a clue but can be unreliable.  Nevertheless, when it suddenly starts rising it may indicate that a further check would be prudent.

The Coronation

Last Time

 

 

When George VI died unexpectedly in February 1952, I was just 6 years old, so the impact of his death on me, despite my parents' laments for a good wartime leader and their sitting up to listen to his funeral on the radio, was not great.

At Thornleigh Primary School school assemblies I was aware that there was a change because the National Anthem changed and we now sang God Save The Queen.

Usually, we would just sing the first verse, accompanied by older children playing recorders, but on special occasions we would sing the third verse too. Yet for some mysterious reason, never the second.

The Coronation was a big deal in Australia, as well as in Britain and the other Dominions (Canada, South Africa and New Zealand) and there was a lot of 'bling': china; tea towels; spoons; and so on. The media went mad.

Renewable Electricity

 

 

As the energy is essentially free, renewable electricity costs, like those of nuclear electricity, are almost entirely dependent on the up-front construction costs and the method of financing these.  Minimising the initial investment, relative to the expected energy yield, is critical to commercial viability.  But revenue is also dependent on when, and where, the energy can be delivered to meet the demand patterns of energy consumers.

For example, if it requires four times the capital investment in equipment to extract one megawatt hour (1 MWh) of useable electricity from sunlight, as compared to extracting it from wind, engineers need to find ways of quartering the cost of solar capture and conversion equipment; or increasing the energy converted to electricity fourfold; to make solar directly competitive.
