Fear

[George Cantstandya]

Fear often does indeed stop death. Well, not really stops it, but certainly can delay it. Example:   "Hey look at that massive bear and its cute cubs."  

Person A: I'm going to go say hello to this bear and try to get a selfie.
Person B: I'm leaving as fast as I can because this isn't safe and I'm scared.

Person A most likely stops their life while feeding the life of the bear and its cubs.  Person B while certainly not stopping their inevitable death has at least delayed it  :)
