I love the writings and work of Charlie Brooker. He writes for the The Guardian newspaper and he covers many diverse subjects in his comment is free column as well as writing reviews and opinions of television. His observations are often incisive and thought provoking as well as being very amusing.
In his latest article he talks about the sudden realisation of self and being alive, or as he puts it “Those late-night moments of lurching fear, of existential nausea, of basic ‘I’m alive!’ horror”
Well worth a read.
