In the 1950s, Yale University graduate anthropology student Dwight Heath traveled to Bolivia with his wife, Anna, to conduct field work for Dwight’s dissertation on the Camba people. Immersing themselves in Camba culture alerted the Heaths to the fact that the Camba regularly drank 180 proof laboratory alcohol at weekly drinking parties. Heath published his findings in the Quarterly Journal of Studies on Alcohol. Despite suffering acute intoxication, the Camba people didn’t exhibit increased violence.
