History of the chainsaw
"The prototype of the chain saw familiar today in the timber industry was pioneered in the late 18th century by two Scottish doctors, John Aitken and James Jeffray, for symphysiotomy and excision of diseased bone respectively. The chain hand saw, a fine serrated link chain which cut on the concave side, was invented around 1783–1785. It was illustrated in Aitken's Principles of Midwifery or Puerperal Medicine (1785) and used by him in his dissecting room. Jeffray claimed to have conceived the idea of the chain saw independently about that time but it was 1790 before he was able to have it produced. .. While a heroic concept, symphysiotomy had too many complications for most obstetricians but Jeffray's ideas became accepted, especially after the development of anaesthetics."

Sudzibas.lv - Latvijas Nacionālā Opera - Briesmīga režija, operas solistu profesinālsis zems līmenis
"Režija ir smaga, cik daudz agresijas, antikultūras propagandas un lepnums par to! Ramona Zaharija pirmos divos cēlienos dziedāja pavirši it kā,, saudzēja savu balss spēkus" trešajām cēlienam, Habanērā neizvilka galvenās notis, ka aktrise nospēlēja lomu pavirši-es nesajūtu Karmenas Kaisli, es sajutu kā tā nav Karmena, bet vienkāršā meitene no krimināla rajona, Karmenai jābūt uguns zem pēdām, tādu raksturu es nesajūt Zahārijas izpildījumā!"
"Viss šausmīgakais skats Mersedes lomā Ilona Bagele !Kur skatās režisori, kolēģ?i!Ilonai ir slikta neatbilstoša skatuves faktūra( liekais svars), bals drebošas skaņas ir nepatīkami klausīties,kustības pārspīlētas,aktiera meistarība pašdarbības līmeni. Nedrīkst pieļaut lai klausītāji dvēsele izmej aktierus un tie izskatās nožēlojami."

Iceland urged to ban ‘blood farms’ that extract hormone from pregnant horses
"Iceland is home to about 80,000 Icelandic horses, 5,383 of which are used as “blood mares”. There are 119 blood farms operating in the country. .. In Germany, 6.4m single doses of PMSG (Pregnant Mare Serum Gonadotropin) – the equivalent of about 32,000 litres of blood – were given to sows between 2016 and 2019, according to the federal ministry of food and agriculture.
PMSG can be obtained legally in the UK from a registered vet, with products available including vaginal sponges for sheep, which induce early lambing, with advertised benefits such as producing lambs “at the optimum time for autumn sales”."

The Modern Diet Is a Biosecurity Threat
"During the late Victorian period, there was clear evidence of a worsening in health. By the Boer War at the turn of the century, 50 percent of young working-class recruits were so malnourished as to be fully unfit for service—a problem that had never been reported during the Asante or Zulu Wars in the early 1870s. In 1901, the British infantry was forced to drop its minimum height for recruits from 5’ 4” to 5’. The British government responded by setting up a “Committee on Physical Deterioration,” in order to address a problem that had not existed a few decades prior."
"The country with the highest prevalence of diabetes is now not the U.S. or Britain, but Pakistan. The countries with the highest rates of obesity are the impoverished statelets of the South Pacific, like Nauru and Tonga, which now neglect nutrient-rich local staples like coconut or breadfruit in favor of processed foods imported from Australia, Vietnam, and Thailand. Even the Yucatec Mayans of southern Mexico have begun to suffer greatly from Western lifestyle diseases."
"Microbiome depletion is likely linked to the growth in mental disorders over the last few decades: researchers have increasingly focused on the “gut-brain axis” and its relationship to mental health. There is substantial evidence that the remarkable increase in depression and anxiety over the last few decades might not just be a product of loosening interpersonal bonds, but also a reverberation of these widespread physiological problems. Common deficiencies in minerals like magnesium, for instance, have been linked to depression and anxiety in women; a number of studies have found a connection between low intakes of Omega-3 fatty acids and depression and bipolar disorder, on both the individual and population levels."
"The simple fact that whole, organic food is expensive creates a class divide in health that is severe enough to be visible in the geography of American cities: the disparity in life expectancy between the Roxbury and Beacon Hill neighborhoods of Boston, for instance, is now about as large as the gap between El Salvador and Finland—with the poorest sub-neighborhoods of Roxbury, like Egleston Square, reporting life expectancies lower than those of Haiti or Liberia."

Regular caffeine consumption affects brain structure
"Data comparison revealed that the participants' depth of sleep was equal, regardless of whether they had taken the caffeine or the placebo capsules. But they saw a significant difference in the gray matter, depending on whether the subject had received caffeine or the placebo. After 10 days of placebo -- i.e. "caffeine abstinence" -- the volume of gray matter was greater than following the same period of time with caffeine capsules. ..
Although caffeine appears to reduce the volume of gray matter, after just 10 days of coffee abstinence it had significantly regenerated in the test subjects."

The Life of a Backpacker in Asia in the 1970s
"I was shooting two rolls of film a day while traveling, about 70 photos. When I was growing up, my family would shoot a roll of 24 photos in a year, which was pretty typical. You'd have three holidays on one roll. It was considered radical, extreme to be shooting as many photos as I was. When I would tell people I shot 70 per day their jaws would drop. They couldn't imagine how you could find 70 things to take a photo of in one day! That many pictures in a day was considered insane."

"De Valk windmill in mourning position following the death of Queen Wilhelmina of the Netherlands in 1962"
"In the Netherlands, the stationary position of the sails, i.e. when the mill is not working, has long been used to give signals. If the blades are stopped in a "+" sign (3-6-9-12 o'clock), the windmill is open for business. When the blades are stopped in an "X" configuration, the windmill is closed or not functional. A slight tilt of the sails (top blade at 1 o'clock) signals joy, such as the birth of a healthy baby. A tilt of the blades to 11-2-5-8 o'clock signals mourning, or warning. It was used to signal the local region during Nazi operations in World War II, such as searches for Jews. Across the Netherlands, windmills were placed in mourning position in honor of the Dutch victims of the 2014 Malaysian Airlines Flight 17 shootdown."

Windows to the Soul: Pupils Reveal ‘Aphantasia’ – The Absence of Visual Imagination
"Exposing participants to bright and dark shapes, the researchers found that aphantasic individuals exhibited the same pupillary response as the general population: constriction to bright, dilation to dark.
However, during the study’s second component where participants were asked to visualise those same shapes, the pupillary response of aphantasic individuals did not significantly differ in response to imagined dark versus imagined bright objects.
“One of the problems with many existing methods to measure imagery is that they are subjective, that is to say they rely on people being able to accurately assess their own imagery. Our results show an exciting new objective method to measure visual imagery,” says Prof Pearson, “and the first physiological evidence of aphantasia. With over 1.3 million Australians thought to have aphantasia, and 400 million more internationally, we are now close to an objective physiological test, like a blood test, to see if someone truly has it.”
To ensure the aphantasic participants were really attempting imagery, the researchers included a further experimental condition, requesting aphantasic individuals to visualise four shapes, instead of one.
While the pupils of those with aphantasia showed no difference when imagining light versus dark objects, they did show a difference imagining one versus four objects, suggesting more mental effort, thereby negating an explanation of non-participation by aphantasic individuals."
