Thing I didn’t know: Stendhal syndrome
Stendhal syndrome is a psychosomatic illness that causes rapid heartbeat, dizziness, confusion and even hallucinations when an individual is exposed to art, usually when the art is particularly ‘beautiful’ or a large amount of art is in a single place. The term can also be used to describe a similar reaction to a surfeit of choice in other circumstances, e.g. when shopping.
I usually just call this Walmart Overload.
