Cold(Холод)

A documentary about a man who solves the problem of individual immortality. He's not going to die. Various options are being considered - from cryonics (freezing of the brain and body), to digital immortality (digitization of consciousness). Note that the hero lives in Russia, where the topic of immortality is practically not explored. However - everything is ahead! Who knows - perhaps this person will be able to become one of the first "immortals".
