Input: George Sands:  The worst thing , the very worst thing , is that it feels so good . A week before I need glasses to watch the news , Mitchell has to open jars for me . Then suddenly everything starts to work . All my senses expand and there 's this part of me that ca n't wait , that 's turned on and hungry . The neck 's amazing is n't it ? This tangle of artery and muscle and sinew . Did you know there are two jugular veins ? An internal one and an external _ one _ . I 've met people what have tasted them . And they said the windpipe came away with a sigh of air from the lungs that was still warm . As they described it they had this look , like everything they do in between is just sleepwalking and it 's only for those few moments that they are totally and truly alive . And there 's part of me that would give anything to feel like they did , to taste what they taste . And that 's the worst thing .
