The idea behind Life is Short can best be summed up as a kind of modern re-imagining of the Roman Stoic philosopher Lucius Annaeus Seneca’s book On the Shortness of Life. Seneca’s main point in his book was that life is not so much short as badly wasted. Since Seneca’s book was written around the start of the first millennium, it is crucial to expand his book using new ideas from philosophy, as well as physics and psychology, that have emerged since his time.
