Those talking points need to be double-checked

Mark Bellis performed a study on life expectancy of rock stars which found that rock stars do tend to die young. From the Reuters story:

American stars Jerry Garcia of the Grateful Dead, Carl Wilson of the Beach Boys and Johnny Ramone of the Ramones all died in their 50s.

Bellis suggested that the high death rate among older American musicians could be related to the continent's greater appetite for reunion tours, exposing the artists for more years to an unhealthy "rock'n'roll" lifestyle.

It could also be due to the poor medical outlook for impoverished American ex-pop stars who have no health insurance, he said.

(emphasis added.)

The financial assets of most rock stars are private. However, for Jerry Garcia, we know more because his former wives fought publicly over his estate. Whatever the cause of Mr. Garcia's heart attack, it was not lack of money.
