The 1980s are famous for wild music, crazy fads, and even crazier hairdos. A new study finds people born in the 80s have a harder time settling down. Those born between 1985 and 1990 were the most likely to split up with their first live-in girlfriend or boyfriend. Scientists from University College London and the University of St Andrews say people born during the 80’s decade are less likely to marry the first partner they move in with. People born in the 1980s are much more likely to move in with a first partner later in life than others born earlier in the mid and late 70s.
