I’m not trying to criticize OP
But I have seen this posted over and over again, and I really don’t understand why it is capturing people’s attention.
Another commenter here pointed out that it’s mystical pseudoscience, and it has no relevancy to anything. (Ed: Unless you want to fund future research and how to create undead soldiers /s)
There’s really no mystery to what happens when a human dies or any other creature for that matter, various electrical impulses continue in various ways, then the creature dies.
Dip your bare feet in a bowl of garlicy water and you’ll taste it
