Tragically unbeyachted.
what is unnatural, then?
Apparently:
In medicine, death by natural causes is a loosely-defined term used by coroners describing death when the cause of death was a naturally occurring disease process, or is not apparent given medical history or circumstances. Thus, deaths caused by active human intervention (as opposed to the failure of medical intervention to prevent death) are excluded from this definition, and are described as unnatural deaths.
...I didn't know that.
