Introduction
Main Idea: Something exciting or mysterious to grab attention—such as, "Before your heart beats, before your eyes close forever, your nose may have sensed the end."
Briefly reference the idea that certain physical signs—particularly around the nose—may indicate declining health or impending death.
Transition to the scientific and cultural observations behind these signs.
Section 1: The Nose Knows—The Scientific Evidence
Changes in Sense of Smell:
How a diminished sense of smell may be linked to neurological decline, especially in older adults.
Cite studies showing that loss of smell function can predict death in older adults.
Possible link to Alzheimer's, Parkinson's, and general cognitive decline.
Appearance of the Nose:
Discuss how the skin around the nose can change color (become pale, bluish, or darker) due to poor circulation.
Medical Signs: Blueness, mottling, or even mild swelling as death approaches.

The ancient idea that the "last breath" comes from the nose.
Myths about the "smell of death" - that the nose picks up certain chemicals when the body stops functioning.
Section Three: The Smell of Death - Biochemically
How the body begins to secrete certain compounds (such as putrescine or cadaverine) shortly before and after death.
There is some evidence that humans may react subconsciously to the smell of death in others - as a fight-or-flight response.
