Oh no lets give you nightmares... this diving accident was recorded by the diver himself - nobody has any clue why but he actually went down like a stone - even when rock formations are in his way he scrapes past them to get even deeper... on the ground he finally looks at his diving computer realizes how deep he is that he has no air left and goes berzerk ... and dies..Scuba diving? no fucking way
Since noone said it. It looks like a splitting head ache.
