Is it possible to die of 'old age'? I understand that as you get older, you're more likely to get cancer, Alzehemiers, etc, but is there such a thing as dying of 'old age'?

This is a good question. This lecture is very informative, please read it.

In most states, death of "old age" is not a permitted reason on a death certificate. Yet some doctors believe it can be a cause when the elderly deceased has multiple causes of death, yet none of them serious enough to kill him.
