I know what you mean, Tim, and there is even what is so bombastically called the science of "erasing death " that can "bring dead people back to life " even after extensive periods of "clinical death " as this following book shows :

But , in fact : that just means that as technology and science advance .... people do get more opportunities to be saved from death , that does not mean they get brought back to life from death .
Once again : to assert that one was "dead " during some minutes or more and then one gets brought back to life is non-sense : when one really dies , one does not come back .
"I was dead for some minutes " and then brought back to life is a contradiction : when you really die , you are really dead = there are no such things as near death experiences , half death experiences , quarter death experiences lol ...
