In a study, researchers from City University London looked at two decades' worth of data from about 300,000 adults. They say your waistline measurement should be no more than half your height in order to live a prolonged life.
According to their developed formula, this would mean the waist of a male adult who is 5 feet 10 inches should be no larger than 35 inches. Similarly, a 5-foot-4-inch woman's waist should measure 32 inches. An increase of as many as 7 inches can trim more than one and a half years off his or her life.
