Ekşi Sözlük gibi, insanların yüzlerini veya isimlerini göstermeden yazabildikleri ve jüri rolünü üstlenip her konuda atıp tutabildikleri ortamlarda oluşan bir "beğenmeme" hastalığı var. Bunu algılayamayıp oradaki yazılanları ciddiye alınca insanın zaten hiçbirşey yememesi, içmemesi, kullanmaması gerekiyor, çünkü hemen her popüler ürünün altına "bokum gibi" yazan dingiller var. Bu dingillerin bazıları o bahsi geçen ürünü hiç kullanmamış (veya yememiş, içmemiş) bile.
 
Mesela (atıyorum) Absolut votka başlığına bakıyorsun. Biri "Smirnoff buna 100 basar, bok gibi votka, sırf reklam" diyor. Diğeri çıkıyor bilgisini ispatlamak için "Absolut ve Smirnoff denen lağım suyunu içeceğime çay içerim. Moskovskaya'nın üzerine votka tanımam" diyor. Başkası çıkıyor Absolut'u yapanın anasını avradını diyor. Hani bilmeyen birisi bu adamları böyle kadrolu barmeni olan villada yaşıyorlar, evde boyuna votka martini filan içiyorlar sanır. Lan zaten o bok attığın şeyi bir kere denemişsin, normalde Tekel votkasına talim ediyorsun, bu neyin artistliği? Bununla kendilerini tatmin ediyorlar. "Öyle havalıyım ki, herkesin beğendiği şeye bok attım, ezdim onu" diyor adam kendi kendine. Sonra gidip otuzbir çekiyor. Sonra ellerini yıkayıp başka bir popüler başlıkta bok saçıyor etrafa.
 
İşte bunlar hep eziklikten. Mesela biz iPhone'a laf ediyoruz ama alamadığımızdan filan değil, almışlığım kullanmışlığım var, yine alırım istesem, bana uymadığı için laf ediyorum. Diğer yandan laf edenlerin yarısından çoğu alamadığı için laf ediyor. Bugün DSG'ye laf sokanların çoğu Volkswagen'in ancak 1/18 modelini alabilecek durumda. Adam Absolut'a, Mercedes'e, Sony'ye, ona buna birşey bildiğinden, anladığından değil, ulaşamadığına bok atarak rahatladığı için bok atıyor. Zaten ismi cismi de belli olmadığı için söve söve ilerliyor başlıklar arasında. Artık antibiyotik mi olur, ampütasyon mu olur, bir şekilde çare bulmak lazım bu hastalığa.

SCIENCE Dead people and pets are being forged into sparkling blue diamonds — here's how
Dave Mosher   Jul 26, 2017, 12:22 PM ET Algordanza/courtesy of Frank Ripka A rough "memorial diamond" synthesized from human ashes. When a person dies, cremation is an increasingly popular option. The practice eclipsed burials in the US in 2015 and is expected to make up more than half of all body disposals by 2020, according to the Cremation Association of North America.
But instead of storing a loved one's cremains in an urn or sprinkling them outside, a growing number of bereaved consumers are doing something more adventurous: forging the ashes into diamonds.
This is possible because carbon is the second-most-abundant atomic element in the human body, and diamonds are made of crystallized carbon. Researchers have also improved ways to grow diamonds in the lab in recent years.
While at least five companies offer a "memorial diamond" service, Algordanza in Switzerland is one of the industry leaders - its services are available in 33 countries, and the company told Business Insider it sold nearly 1,000 corporeal gems in 2016. Algordanza also claims to be the only company of its kind that operates its own diamond-growing lab for cremains - one of two in the world. (The other is in Russia.)
"It allows someone to keep their loved one with them forever," Christina Martoia, a spokeswoman for Algordanza US, told Business Insider. "We're bringing joy out of something that is, for a lot of people, a lot of pain."
Here's how the company uses extreme heat and pressure to turn dead people - and sometimes animals - into sparkling gems of all sizes, cuts, and colors.

Making a diamond from a dead person begins with cremation. The process typically leaves behind about 5 to 10 pounds of ashes, much of which is carbon.

  Martoia said Algordanza requires a minimum of one pound of cremains. "That's kind of the magic number, where our engineers can guarantee there will be enough carbon to make a memorial diamond," she said.
Algordanza   When the company receives ashes from a customer, a technician puts a sample into a special oven to see if there's enough carbon to grow a diamond. If there's not enough, the amount of carbon in a lock of hair can make up the difference.
   
  Once there's enough carbon, the element is extracted and purified of contaminants like salts. "We use an acidic chemical to get rid of impurities," Martoia said.
   
  This bumps the carbon purity of the processed ashes to about 99% or greater.
   
  The other 1% contains impurities like boron — an element and micro-nutrient that helps humans (and other animals) grow bone, heal wounds, and regulate the immune system.

  Boron is the impurity that colors the rare blue diamonds found in nature — and is why many "memorial diamonds" come out blue, too.

  "The diamonds can range from clear to very deep blue," Martoia said. "The more boron, the deeper the blue."

"But an interesting thing to note is that our technicians are seeing a correlation in people who have had chemotherapy. Their diamonds tend to come out much lighter," Martoia said. This may be because chemotherapy leaches away the body's boron and other important micronutrients.
  When Algordanza processes ashes, Martoia says, "it's nearly impossible to separate out the boron from the carbon". This is because the two elements share similar weights and properties.
Sandbh/Wikipedia (CC BY-SA 4.0) Boron and carbon are similar in size and other atomic properties.   To further purify the carbon to 99.9% or more, technicians pack it into a growing cell that contains iron and cobalt — additives that help remove contaminants.
   
  The cell also contains a tiny diamond to help the carbon crystallize into a rough shape, since carbon crystallizes best when it touches an existing diamond.
Algordanza The diamond provides a "blueprint" for the carbon to work from, which means the new diamond that eventually forms will require less cutting and polishing.
  The final purification step converts the carbon into slippery sheets of graphite — the same type of carbon in pencils. Graphite's microscopic flat sheets of carbon are an ideal starter material for synthesizing diamonds.
Algordanza   Natural diamonds form out of carbon that gets stuck in lava tubes about a mile deep in the Earth's crust.

Algordanza   That machine can heat a growth cell to nearly 2,500 degrees Fahrenheit. It also squeezes the cell under 870,000 pounds-per-square-inch of pressure.

After 10 months of growth, the resulting gem actually wound up being 1.76-carats - but it's still the largest memorial diamond ever made by the company.
  Orders for diamonds made from human cremains aren't the only type that Algordanza receives. "First we had the cremains of a German Shepard and now we have cremains of a cat," Martoia said.
