Something to keep in mind — You Are Dying Every Day:

It’s easy to see death as this thing that lies off in the distant future. …We think of dying as an event that happens to us. It’s stationary—whatever date it will happen at—and we’re moving towards it, slowly or quickly, depending on our age and health.

Seneca felt that this was the wrong way to think about it… Instead, he said, death was a process—it was happening to us right now. We are dying every day, he said.
