Death awareness has been attributed solely to human Beings. Most natural is the actualization of the awareness of death in connection with ageing. Therefore awareness in situations where there is actual danger to one’s life can be considered a key element for self-preservation and mission accomplishment. This awareness presumes concrete or situational thinking in order to take the most suitable “maintenance decisions” and expand/improve the lifespan.
