Even the impact of nervous and psychological shocks can be understood on the basis of being heavy strain
Fatigue is a word of wide meaning
include physical and nervous fatigue due to physical causes such as lack of sleep or poor nutrition or excessive effort in the work
it also includes nervous stress resulting from confusion of psychological shocks
Fatigue could also be a cumulative result of lack of sleep or overwork for several days or the result of several successive bad news,....or it may be intensified fatigue as a result of one strong shock.
In all cases,the reason why most people will be killed would be the extreme fatigue,
mental turmoil in itself does not kill whatever was its magnitude unless it result in high Fatigue.
Based on all this,it is clear that there is a thorny problem,
which can be summarized in this question:
when will a person be entitled to assume that the time of the crisis has passes off peacefully??
when will he be sure of the stop of the process of liquidation and the end of the spread of sudden death??
This question is of profound significance,
As long as the cause of death is high fatigue,
and this fatigue is cumulative in nature,
most individuals who will cross the peak time would remain threatened to fall as a result of the accumulated fatigue.
