It is proposed that biological aging mainly depends on a deleterious accumulation of insoluble inert protein that has escaped physiological proteolytic degradation. Intracellularly, a three-dimensional network of polypeptide chains may exclude macromolecular structures and organelles from part of the cytosolic water. In this way vital intracellular transport mechanisms may be obstructed, providing a rationale to several observations linked to aging.
