Solo rock stars are twice as likely to die prematurely as counterparts who perform in groups, a study published in the journal BMJ Open said.
British researchers examined the fate of 1,489 rock and pop performers who had risen to fame in a study period that spanned half a century. A total of 137, or 9.2 percent, died prematurely, at 45.2 years of age on average for North American stars and 39.6 for those in Europe.
Substance abuse and car crashes accounted for nearly 40 percent of deaths, according to the probe.
Among the 114 US soloists documented in the study, 23 percent died at a younger age than the general population. In Europe, too, 9.8 percent of soloists died young, compared to 5.4 percent of group performers. Stars who became famous before 1980 were much likelier to have died young.
