"What one learns in early life tends to persist more than what is learned in later life. Certain sexual tendencies, speech habits, gestures and facial expressions, fear of black magic and wicked spirits, and fondness for certain foods--all of which are associated with early learning--are among the most difficult of habits to change. Voodoo persists for a variety of reasons, not least of all because it is associated with early life experiences. Health programs meet stiff opposition when new dietary habits are suggested because they go counter to the pleasant and satisfying childhood experiences associated with eating."
