What does call no man happy who is not dead?

Call no man happy who is not dead because only after a person has died can we truly assess their life and its impact. While a person is alive, there is always the possibility of change, failure, or misfortune, which could alter our perception of their happiness. Furthermore, it is only after death that we can see the final outcome of a person's life, which can shed light on whether they truly achieved lasting happiness.
