Daniel Goleman states: “Each successive generation worldwide since the opening of the [20th] century has lived with a higher risk than their parents of suffering a major depression — not just sadness, but a paralyzing listlessness, dejection, and self - pity, and an overwhelming hopelessness — over the course of life.
Dr Daniel Goleman teatab: „[20.] sajandi algusest alates on üle maailma igal järgmisel põlvkonnal olnud suurem risk kui nende vanematel langeda raskesse depressiooni, kusjuures tegemist pole mitte lihtsalt kurvameelsusega, vaid halvava tuimuse, masenduse ja enesehaletsuse ning kõikehaarava lootusetusega.
