How creative and at the same time terribly "ugly" humanity is.

But that’s not what we’re talking about... There is a very strange and quite interesting phenomenon that gives rise to myths and is a waking nightmare. So, this is sleep paralysis: the ins and outs of nightmares.

There is an opinion that the largest living cell is the ostrich egg. An African ostrich egg can reach a height of more than 17 cm and weigh about 1.5 kg, but this does not make the ostrich egg the largest cell known in nature. For example, a giant squid nerve cell can reach 12 meters in length. In the plant world, the cell of Caulerpa (seaweed) has many nuclei, and it can grow up to 3 m in length. If we nevertheless consider the egg of the largest bird, then, most likely, the egg of Epyornis (an elephant bird reaching a height of 5 m) would be one of the largest. Unfortunately, this species is considered extinct (destroyed by humans in the 17th-18th centuries), although eggs of this legendary bird are still found.

The resulting product is fermented by saliva and begins to ferment. The final product is a low-alcohol drink similar to beer and is Chicha. Chicha is jokingly called “spit beer.”
