So, are there real life examples of something dead coming back to life? In fact, there are. There are three aspects to consider.
One truly frightening aspect is that sometimes lay people and even medical professionals aren’t all that great at determining whether or not a person has a pulse. This influenced changes to how the American Heart Association teaches CPR. Now, it’s encouraged to not spend more than 10 seconds trying to figure out whether or not a person has a pulse. If they’re not responding to you and you can’t find one—just start CPR. If they are conscious, they’ll let you know. If not, they likely need CPR anyway.
Three: Are there real-life examples of things that are truly dead—no pulse, no breathing, no brain activity—yet, come back to life.
Let’s take the case of the wolf spider. A French researcher, Julien Petillon, decided to find out and submerged them in water for several hours—like 16. Now dead, they did come back to life.
