These are three variants of premature dead.

 A first,am shared, as when all tasks done , and not mind a future for energy lost.

Second ,when a soul categorically is not doing before a her on a stage these tasks realizing,and here also a loosing sense a soul having in this body and he is dead. As in hard disease,and given a possible find a method for a comfort staying with this disease.And human lives a full life with this disease,when an other with this disease are all life surviving.And logically  ,that he must an own knowledge's about a how comfortable a live in this disease condition and-give to other. And he having a possible to do this,but he is keeping an own unique knowledge's and not sharing with an other as having in same position.Thus a life mean his is loosing and conditions creating in which he is dead. As third variant meeting in children's , and famous peoples, and this variant for meaning is more,than a future his life.And a useful for peoples , which gives a community resonance on his dead is a importance ,than his life prolong. And example for this dead is a Elisabeth Glinka with ensemble Alexandof in aviation disaster.And a reason for dead lie in thin plan and realization these reasons is going on material level and may realize by a different ways.And this is an oncology, accident and etc..

And  therefore you are doing a business , by way a soul and incarnated,till you are doing are tasks, are put before her, he is not dead. And who want a live longer ,thus need to understand,that his life prolong depends from a right theirs behavior. 

 The end.
