Misery Begins at 70

After years of listening to the lament "It isn't the heat, it's the humidity," the U.S. Weather Bureau has finally decided to warn--or at least try to warn--people when a particularly sticky day is in the offing. By the time next summer's heat and humidity come along, the forecaster will have a "discomfort index" that combines both the air's temperature and the amount of moisture in it. Under the formula, explains Climatologist Earl C. Thorn, a discomfort figure of 75 might mean 80DEG temperature and 60% relative humidity, or it could mean 85DEG temperature and 30% relative humidity, or 75DEG temperature, 100% humidity. All are unpleasant. Thorn estimates that 10% of the population can expect to feel uncomfortable before the index reaches 70. When it reaches 75, half the people are uncomfortable. At the index of 79, everybody is uncomfortable.
