No bad answer anyway
Have you ever thought about what it means to exist? It’s clear that for most people, “existing” means breathing and thinking ,but that’s not really the case. A human being constantly creates and destroys millions of cells. So the “me” of yesterday is no longer truly the “me” of today.
So if the “me” of yesterday no longer exists, and the “me” of today will no longer exist either, am I really existing?
Yes. Which means the question of existence is not physical. The brain changes too, what I liked yesterday, will I still like tomorrow?
In that case, is the “me” of yesterday physically and mentally dead?
No. Because in truth, we never really die. The “me” of yesterday lives on in the minds of those who know me, as long as they remember me. Our most precious legacy is the memory we leave behind, because it allows us to keep living even after our “death.”
