El susto, the anthropologist Linda Green wrote, was “understood by its victims to be the loss of the essential life force as a result of fright.” In more conventional terms, its symptoms included depression, lethargy, insomnia, nightmares, diarrhea, and vomiting. To anyone mindful of La Violencia of the war years, the connection to post-traumatic stress was unavoidable. These conditions were, as Green put it, “social memory embodied.”
