Has anyone you know died a tragic death and it made you think about the seriousness of life?

I don't know if this is tragic.At the corner of our neighborhood lived an oldman.He might be around 70+ and lived alone.One night,a lady ran out of his house crying for help...People ran towards his house only to find him unconscious and naked with semi erection.Ambulance was called.But halfway to the hospital he died.It became a case and police investigated that lady.She confessed that she's a prostitute whom he hires frequently since his wife's death.During one such session,the guy passed out for unknown reason during the intercourse and said incident followed.
Police closed the case citing death due to Viagra OD and left the woman.
This incident often makes me reflect life sometimes (though in a funny way; Don't mistake me.Sorry.I just was open about how I feel regarding this matter).
