Death and laughter? This genre does not yet have a name in science. However, the reader soon discovers that, with a humorous sauce, he receives valuable information about something that worries him, but is often not customary to discuss. Little by little we learn about the attitude towards human mortality in various cultures and religions, about the evolution of philosophical approaches to the topic of life and death, about modern human strategies, if not to ensure immortality, then to extend life for an indefinitely long time. And, in addition, we will find out which of the title characters of the book “Heidegger and the Hippopotamus Enter the Gates of Heaven” will manage to penetrate through them. Does Eternity dwell in the other world? Or is it lurking somewhere here, in the neighborhood? If so, who has will there be time for it? Do we have an immortal soul? Where is it? Is it possible to sell it on eBay? [28] Is it your recently deceased Aunt Lulu calling? If so, does that mean it's rude to hang up? Will death be defeated in the new millennium? Is this book even necessary? And more importantly: if not, can I get my money back? It won't end as long as that fat lady sings. Oops! She sings.
