The BBC reports that sperm quality continues to drop. Specifically, researchers "found a 52.4% decline in sperm concentration, and a 59.3% decline in total sperm count in men from North America, Europe, Australia and New Zealand." While alarmist publications tout this as a 60% drop, the decline is accelerating and the researchers are concerned that inaction may lead to species extinction despite the effect not being observed in regions with high machismo, such as South America, Asia and Africa.
The study "aggregates 185 studies between 1973 and 2011, one of the largest ever undertaken." It supposedly overcomes selection bias occurring from patients attending fertility (virility?) clinics and selection bias of null results not being published in journals (churnals?). My intuition is that insights can be gained from studying transsexualism. Practitioners claim patients increase at the rate of 15% per year (doubling every five years), over many decades and with no end in sight. This is akin to Moore's law, Kryder's law, Butters' law, Hendy's law, Rider's law, Carlson's law or any other exponential halving or doubling. So, it doesn't take a genius to understand that it will become an increasingly widespread issue.
Regardless, masculine medical problems are vastly under-represented. By some estimates, spending on male medical problems is about 1/4 of spending on female medical problems. For example, when a man seeks help for a legitimate medical issue, such as declining testosterone, a patient at the lower end of the "normal" range may be denied treatment even if he is constantly exhausted.
Well, take care of yourself. Eat properly. Drink properly. Rest properly. Stay active. And if healthy food and exercise won't fix accumulated problems, consider hormone replacement. You may also want to watch two films which seem to be mentioned with increasing frequency and seem to predict our era with some accuracy: Children Of Men and Colossus: The Forbin Project. Children Of Men is the second bleakest film I've ever seen and the film I've seen most during its initial cinema release. It explores the scenario of global infertility leading to economic collapse. In addition to a nexus of cast and crew, the seamless plot and astounding compositing, the film is a fantastic example of mise-en-scène which is best explained by example.
Anyhow, enjoy the films and get your medical problems addressed.
When I visit a poorly electro-mechanical engineer, we often watch two episodes of a television series. Indeed, my friend often watches fiction in two episode chunks because this is similar to the duration of a short feature film. Previous visits included the first two episodes of Breaking Bad , the next two episodes of Breaking Bad, the first two episodes of Continuum and the first two episodes of Dark Matter . To indicate the quality of The Expanse , we watched four episodes in one sitting. This is unprecedented for us.
The Expanse, which airs on the SyFy channel in the US, is set in a future where most of the solar system is colonized with ethnically diverse people who retain their languages, customs and fashion. One character has a notably heavy Afrikaans accent. A Martian captain has a distinctly Chinese appearance. However, people remain tribal; mostly Earther, Martian or Belter. This is a future where your gravity well means more than your genes. Belters provide water and minerals. Mars has its own industrial base and technology. Unfortunately, like the Philip K. Dick story The Crystal Crypt, Earth and Mars are on the brink of war and any random event could be the catalyst. Mars is resentful of Earth's squandered resources. Earth tortures Luna dissidents. Terrorists and sympathisers are widely suspected.
Higher education is generally a poor deal. A good course at a good institution will boost a career but the vast majority of higher education options are worthless or detrimental. Despite this, people are willing to get themselves into maybe US$100,000 of educational debt. Meanwhile, Ivy League faculty salary often exceeds US$150,000. What do students get for a lifetime of debt? Weed-out classes with a 50% failure rate then top grades awarded with abandon. An increasingly long-tail of third-tier academic journals which are full of bogus results. (A racket within a racket.) Deluxe gymnasiums and student accommodation with en-suite bathrooms. And, in some cases, pressure on staff to ignore plagurism; often due to financial or cultural reasons.
Yes, there's the social aspect and in-person interaction but why is online education seen like a poor substitute along with correspondence courses, vocational courses and community colleges? And here's a humdinger: Why don't the best educational establishments have ISO9000 certification? Are the inputs too variable or is the process too scattershot? Actually, how efficient is education? Are these guys with the US$150,000 salaries even 1% efficient at teaching? I doubt many of them care.
So, what's the Shannon channel capacity of education. Who knows? That's a really poor state of affairs. In the 1940s, telcos knew more about their operational efficiency than educators know now. So, how effective could an education be? How much can we accelerate learning? With CAL [Computer Aided Learning] running since the 1960s we should achieve small miracles. Well, it works brilliantly in limited domains, such as numeracy and vocabulary but the bulk of CAL, educational videos, are a sea of unending dross. So far, I've sat through 18 out of 42 hours of Buckminster Fuller and nine hours of Stanford cultural history. Computer history was the most enjoyable. There's no shortage of content. It ranges from whizzy edutainment to excruitiating virtual blackboards.
