How long does the brain live after death?
Bone, tendon, and skin can survive as long as 8 to 12 hours. The brain, however, appears to accumulate ischemic injury faster than any other organ. Without special treatment after circulation is restarted, full recovery of the brain after more than 3 minutes of clinical death at normal body temperature is rare.

What causes the bloat stage of decomposition?
Decomposition of the gastrointestinal tract results in a dark, foul-smelling liquid called “purge fluid” that is forced out of the nose and mouth due to gas pressure in the intestine. The bloat stage is characterized by a shift in the bacterial population from aerobic to anaerobic bacterial species.
Why do smells bother me?
