Person vs Biology

The visceral struggle against the inherent limitations of the flesh, focusing on genetic decay, disease, mutation, and the inescapable reality of mortality.

The visceral fear of one's own body betraying them, the horror of disease, mutation, or the slow decay of mortality. It is the dread of the flesh itself becoming the enemy.
