Death

So I've died, or completely flatlined at least 4 times (It's why I have a pacemaker now). But after 15 seconds (Not that long to be dead, but still dying a few times is strange) my body did what is pretty much cpr on itself via constriction of muscles. Ever since I found this out I've changed a lot. Including a new value of what life is. This being said, does anyone else ever feel all of the overblown death in horror movies makes us devalue our own lives?
