Good vid.....
Expanding a little on what was presented.... "Biological life" does not cease when the heart stops beating. There isn't a doctor, paramedic, lifeguard or fireman that thinks this, it's the very principle of 'resuscitation' and heart defibrillation employed to overcome "death" simply BECAUSE though the heart has stopped beating, the spirit has not departed, the soul has not ceased to exist. Neither has 'life' ended just because brain activity has stopped.
In my line of work- which I've never spoken much about here- we 'resurrect the dead' in a manner of speaking. At a cellular level, human tissue remains alive-- viable and valuable long after a person dies. We harvest live cells from dead people. --as odd as that sounds, it's exactly what we do. I'll use bone graft as an example. Though the person has deceased, bone material- including marrow is collected and carefully cryo-preserved within a short window of time (72 hours or so) after death and within this window the bone cells (mesenchymal stem cells- osteoprogenitor cells) are still very much 'alive.' We collect, preserve and re-sell these live bone products that are then used in surgery to repair fractures, fuse vertebrae, fill voids, etc. In the cryo-preserved state they have a freezer life in excess of two-years within which they can be thawed and implanted into a patient- wherein they 'come back to life' and once again become part of that person-- bone for bone.
Interesting eh?
