SPIEGEL: Dr. Parnia, in your new book on resuscitation science, “Erasing Death,” you state: “We may soon be rescuing people from death’s clutches hours, or even longer, after they have actually died.” That sounds a lot like resurrection. Is this a serious claim?

Parnia: In the past decade we have seen tremendous progress. With today’s medicine, we can bring people back to life up to one, maybe two hours, sometimes even longer, after their heart stopped beating and they have thus died by circulatory failure. In the future, we will likely get better at reversing death. We may have injectable drugs that slow the process of cell death in the brain and other organs. It is possible that in 20 years, we may be able to restore people to life 12 hours or maybe even 24 hours after they have died. You could call that resurrection, if you will. But I still call it resuscitation science.
