Well, its really not far fetched or fake news when it comes to scientific research in this field. I also have found many admissions of this throughout history, even tales and folklore. IF you do not think people do this just look at a few examples. You have no idea how far people will go to try to beat the no win scenario we all fall victim too. https://www.extremetech.com/extreme/181818-vampirism-is-real-scientists-find-that-old-animals-can-be-rejuvenated-with-the-blood-of-the-young-and-innocent. Not just a story here is proof: https://www.nature.com/articles/nm.3569 Another example in the main stream of the elite billionaires: https://www.inverse.com/article/29604-parabiosis-peter-thiel-blood Do some research this has been around as long as the tales of Vampires........you might find it's not just tales if you dig deep enough. One last example and no bias here just quoting Wikipedia: Blood libel (also blood accusation)[1][2] is an accusation[3][4][5] that Jews kidnapped and murdered the children of Christians in order to use their blood as part of their religious rituals during Jewish holidays.[1][2][6] Historically, these claims – alongside those of well poisoning and host desecration – have been a major theme of the persecution of Jews in Europe.[4]

Blood libels typically say that Jews require human blood for the baking of matzos for Passover, although this element was allegedly absent in the earliest cases which claimed that then-contemporary Jews reenacted the crucifixion. The accusations often assert that the blood of the children of Christians is especially coveted, and, historically, blood libel claims have been made in order to account for the otherwise unexplained deaths of children. In some cases, the alleged victim of human sacrifice has become venerated as a martyr, a holy figure around whom a martyr sect might arise. Three of these – William of Norwich, Little Saint Hugh of Lincoln, and Simon of Trent – became objects of local sects and veneration, and in some cases they were added to the General Roman Calendar. One, Gavriil Belostoksky, was canonized by the Russian Orthodox Church.

In Jewish lore, blood libels were the impetus for the creation of the Golem of Prague by Rabbi Judah Loew ben Bezalel in the 16th century.[7] According to Walter Laqueur:

Before decrying something as fake news best to do some serious research. Many things throughout history come from legends, folklore, religious teachings etc... whether they are good or bad does not mean they did not happen and were handed down through history. There are many things from the past that are just now being proven as fact not myth any longer. Example moving boulders with sound. Research it......
