There are discontinuities in brain state we are willing to accept: sleep, drug use, travelling the world for a year. There are those we are not: Death, Alzheimer's, radical personality change. Have you ever known someone who got in a relationship, or went to a foreign country, or took a job that seemed to really change who they were? Has that ever made you sad? What do you think it means to grow apart? You don't want your friends to die, but you also don't want them to change so much that they aren't your friends any more. Death is a very great and permanent discontinuity, but nothing else about it makes it special.
