Human Survival is subject to a delicate balance between physical laws and social influence. Optimum conditions require adaptation to lawful constraints, resilient social bonds, and secure sites of collective habitation. Survivability tests the capacities of living organisms to tolerate stress, strife and strain in daily life. Human struggle is revealed in a shared resolve to live with nature and nurture in a balanced state of co-existence. Generative life expectations promote optimistic views of longevity. Abiding life force opens up diverse options to live long and live well. Personal competence and relational compatibility test the conjunctive strength of working agreement and mutual understanding against the disjunctive weakness of working disagreement and mutual misunderstanding. The search for a good life must be earned, not presumed, through labor-intensive efforts to secure egalitarian relations with significant others. Constructive alliances maximize gain, minimize loss, and enable resourceful persons to discover purpose, meaning and fulfillment of their highest aspirations.
