E.M. Remarque, "Heaven Has No Favourites/Borrowed life"

They say, live your life like it's your last day on the Earth. Does anyone who is pretty sure they will be alive tomorrow, next month, next year is able to take this wish seriously? Usually we think of death as something inevitable and far... People perceive death as reality only when it comes close to them, either sidewards, or in direct way. Then we forget about it until the next convergence.
 
What is life when death is not an abstraction, but a continuous, albeit unseen companion? It's quite symvolic that Remarque has chosen a young beautiful lady as the death's keeper. Ultimately, death and beauty are correlated: someone thinks death is beutiful, others that beauty has a short life.

Though Death along with Life is the main heroine in the novel, the story doesn't leave a tragic trail after reading. Probably, because the end was already clear from the outset.
