And the Cold War arms race was bipolar, since it mainly involved the opposing powers of the U.S. and the Soviet Union. But the word is encountered most often today in bipolar disorder, the newer name of what used to be called manic-depressive illness, in which the person tends to swing between the two extremes, or poles, of high intensity and deep depression, with depression being the main condition.
