I think grenoire is asking that should over-eating because one is in despair and dying due to health-related diseases be included in that statistics. What about adrenaline-junkies that might be doing it due to despair. I think your question is: Everything being nominal in an average human's life, what's the age where natural systems cause death?

There some research that there is a set amount of beats per life. >Studies have concluded that all mammals get about a billion heartbeats per lifetime. http://robdunnlab.com/projects/beats-per-life/ http://robdunnlab.com/projects/beats-per-life/
