English actor Stephen Fry, who suffers from bipolar disorder, recounts manic behaviour during his adolescence: "When I was about 17 ... going around London on two stolen credit cards, it was a sort of fantastic reinvention of myself, an attempt to. I bought ridiculous suits with stiff collars and silk ties from the 1920s, and would go to the Savoy and Ritz and drink cocktails." While he has experienced suicidal thoughts, he says the manic side of his condition has had positive contributions on his life. The nosology of the various stages of a manic episode has changed over the decades. The word derives from the Ancient Greek μανία ("manía"), "madness, frenzy" and the verb μαίνομαι ("maínomai"), "to be mad, to rage, to be furious".
