The most dangerous profession of them own? I dunno… bullfighter? Garbage man? Singer with a pop band? No, singer with a pop band is deadly for sure, all the travelling with a dozen or so groupies and handlers unable to say put down that needle right this minute.
According to CBC.ca: "Researchers from Liverpool John Moores University and Britain's Health Department studied 1,489 rock, pop, punk, R&B, rap, electronica and New Age stars who became famous between 1956 and 2006 — from Elvis Presley to the Arctic Monkeys. They found that 137 of the stars, or 9.2 per cent, had died, representing "higher levels of mortality than demographically matched individuals in the general population. The researchers dismissed the "fanciful but unsubstantiated" popular myth that rock stars tend to die at 27 — as Jim Morrison, Jimi Hendrix, Janis Joplin, Kurt Cobain and Amy Winehouse all did. The average age of death was 45.2 years for North American stars and 39.6 for European ones."
Here is another reason: as a solo artist the responsibility for the livelihoods of everybody in the entire infrastructure of your success rests and the pressure is much higher and the loneliness much worse. The Rolling Stones masterful "Memory Motel" discusses in detail the hazards of touring, maybe the loneliest of all rock activities (though I know many people who like it till they've done it a great deal) :"My nerves are shot already, he road ain't all that smooth. Across in Texas is the rose of San Antone, I keep on a feeling that's gnawing in my bones" You know what it's like when you wake up at 2am to a world of infinite loss and darkness? And do you know the DTs after a three week bender? The shaking suicide, worthless end of the world as we know it shake it baby rolling on the floor and groaning DTs? Well mix em up and you have the mindset of a rock star and stir in even more loneliness for the pop star, and there you have it in a nutshell.
So IF you are gonna be a pop star and don#t wanna die young don't be Justin Bieber be Harry Styles.
