Question

Shakespeare's Macbeth, Act V Scene 5

Answer 1

It's essentially time and age. So, death would be the most applicable answer.

Answer 2

It refers to Death.

This famous soliloquy is referring to the passing of time, its meaninglessness and our human incapacity to apprehend life as something that would make sense. Instead, life proves to be a story “told by an idiot, full of sound and fury, signifying nothing”. Death then creeps in, slowly but certainly, in every human action, day after day, without recourse to any form of solace. Death is not only inevitable, it is our destiny.
