Death Foresight

I am capable of seeing exactly when people die.  The thing is, I don't know how or why, just when.  The best way I can describe it is to relate it to Death Note.  In the anime, a girl gains the ability to see exactly when a person will die due to a technicality made by a shinigami.  But that's where it differs the most, I had always had this power.  And it wasn't until recently when I started seeing numbers just above the person.  Before, it was just a very strong inclination (for a current lack of a better word).
