Hopefully Anonymous- Agreed. It is ALL just brain chemistry. THIS is where existential angst comes from, the fear and repulsion at the aesthetically displeasing idea that all of these intense, exciting, horrible, wonderful, all-consuming, passionate feelings have NO REAL MEANING, could be induced with a savy enough pill, a simulation, or a puppet show, that your lover and your connection is an emergent phenomenon of evolution, and then you disintigrate into heat and die and narry a memory of what you experienced exists to reverberate throughout a cold, careless, meaningless universe. That is what many people cannot stand to think of. Not- 'Oh, woe is me! Chocolate doesn't please me anymore!'

People want immortality in the worst of ways!

Or they wish no longer to be.
