At what moment are you dead?

For as far back as we can trace our existence, humans have been fascinated with death and resurrection. But is resurrection really possible? And what is the actual difference between a living creature and a dead body anyway? Randall Hayes delves into the scientific theories that seek to answer these age-old questions. [Directed by Anton Bogaty, narrated by Addison Anderson].
