>>13302141Awareness recedes and you fall into a slumber as your neurons fire unregulated. Your body stops working. Cells starve for oxygen, and stop their function causing organ failure. Internal cell signalling causes some cells to begin self destruction. Other cells swell and burst, others shrivel, unable to keep a water balance. Biomolecular processes use up reaction reagents and reach a chemical and electric equilibrium with each other and the environment. The body begins to decompose. Bacteria, fungus, and scavengers feast on the raw detritus. Entropy takes over.
On the other hand, the afterlife is whatever it is you created --- the stability you left behind in the world of the living.
