Autolysis

Over the metal surface
Your body wrapped in a white sheet
Your skin a purplish-gray
These signs indicate early stage of decay

Far from being dead
A decomposition body is teeming with life
A vast and complex ecosystem emerges
As the decomposition unfolds

Starting a few minutes after death
A process called autolysis or autodigestation
Enzymes digest cell membranes
Intracellular space destroyed
