The only sense wired straight to memory and emotion, skipping logic entirely.
means The sense of smell — the process by which the nose detects airborne chemicals and the brain reads them as odor.
from From Latin 'olfacere,' meaning 'to smell,' itself a fusion of 'olere' (to smell, to give off an odor) and 'facere' (to make or do). So the word is literally built as 'smell-making' — the nose doing the work of turning molecules into meaning.

- detection range
- humans distinguish over one trillion distinct odors
- memory link
- olfactory bulb sits next to the hippocampus and amygdala
- decline signal
- smell loss often predates Parkinson's and Alzheimer's by years
