A Short Life Expectancy Job

CNN reports:

World`s oldest person dies at 114

I see this headline about once a month. Uneasy lies the head that wears the crown.  Is it a conspiracy? Perhaps there`s some sicko serial killer out there stalking each successive world`s oldest person. Whatever, it`s clearly not a career with good job security, so I don`t see why people seem to be dying to get the job.
