Is Death Reversible? Is it the right time to find out?

"Death is defined as the termination of all biological functions that sustain a living organism.

Brain death, the complete and irreversible loss of brain function (including involuntary activity necessary to sustain life) as defined in the 1968 report of the Ad Hoc Committee of the Harvard Medical School, is the legal definition of human death in most countries around the world.

Either directly through trauma, or indirectly through secondary disease indications, brain death is the final pathological state that over 60 million people globally transfer through each year.

We are repeatedly told through the medical establishment (as well as through popular culture, in recent public cases such as those surrounding Jahi McMath and Bobbi Kristina Brown) that brain death is “irreversible” and should be considered the end of the line.

Or is it?

Have we come to a technological point where we are able to “push the envelope” to see if this is truly the case?"
