OMG, I need to take my biology and physics science classes again...anyways agrees that professor has a brain; when did we realise this hundred or 2 hundred years back.

Prior to that everybody thought that Heart is the controller (epicentre) of your life and if heart stop working you are dead;
Now clinically it is proven that if brain stop working a man is clinically dead even though his heart is beating (generally in COMA cases). I do agree that there are certain scenarios where science and its great technology could not prove what they claim.

Similarly we always find (see around) that Faith is Mightier than Reality.

BTW: Let me very clear that it is all about once FAITH and everybody should try and search for his CREATOR and identify the SUPERNATURAL and the OMNIPOTENT.
