People do not change over time. The elderly are, in reality, aged tikes. Conversely, the young are juvenile codgers. Granted, we might develop some skills, achieve some profound insights over a lifetime, but by and large who you are at eighty-five years old is who you were at five. One is either born intelligent or not. The body ages, grows, passes through near-lunatic phases of reproductive frenzy, but you are born and die essentially the same person.
That… that is the proof of your deathless soul.— Chuck Palahniuk, Doomed
