Lets say a guy just dropped dead of a heart attack, no pulse, stopped breathing. Now this wizard is right beside him but does not have the right spells to deal with this. So, in a moment of desperation, he casts animate dead and tells the new zombie to have its heart beat. Can we give that specific of a command to a zombie? Would this restore the guy to a long enough life to get him to a healer for a proper healing? Or since he now has a working ticker and is alive again does animate dead stop working on him and thus he goes "Oh darn, my heat just stopped again, I tell you, this is the most annoying thing ever." My outside the box thinking for the day.
