What is the life expectancy of a jazz musician?

The life expectancy of a jazz musician is no more or less than any other musician unless he has underlying health concerns.

I don't know the life expectancy of musicians who play other genres of music but the life expectancy of a jazz musician has been calculated to be only 37 years old. It may be hard to believe but it's true. Of course, many live to a ripe old age but, nevertheless, so many have died young that even with the less stressful lifestyles that today's jazz musicians have compared, say, to those of the 1950's and earlier that it will be a while before this average rises appreciably.
