How we can predict that when we will die?
“Old age” is not truly a cause of death in and of itself. To “die of old age” means that someone has died naturally from an ailment associated with aging. The same usually goes for “dying of natural causes.”
Traditionally, government health authorities have required resident’s causes of death to be listed on death certificates. So, sometimes when an elderly person passed peacefully and not altogether unexpectedly, coroners would simply declare that the deceased had died of “natural causes” or even “old age.” In these cases, there was always a more specific cause of death, but it may not have been determined or thought to be worth mentioning.
