"Neuroscience is the rather medical study of brains. Dr. Cheung does groundwork in uploading, which would be the instantiation of a person's mind in software; it's at least sixty years away, even optimistically, but if it works it could mean universal immortality, and depending on some other factors possibly resurrection of adequately stored deceased individuals. I pay him a salary, reimburse him for research expenses, and provide software support, and I'll pay his assistant too when he finds one he likes, because that seems very cheap for universal immortality."
