The following answer addresses the fact that those who have a spouse die in older age are more likely to die earlier than those who haven’t (re:http://www.straightdope.com/columns/read/2705/when-one-spouse-dies-does-the-surviving-spouse-tend-to-follow-soon-afterwards).
My question for this is a little more specific in the difference between Windows and Widowers. I have heard it said that, statistically speaking, an Widow will generally live longer after the death of a spouse than a Widower.
This would imply something like the following (number are made up examples): After the death of his Wife a man will live 5 years on average whereas after the death of her Husband a woman will live 7 years on average. I am curious if anyone has ever run across data like this to support or refute this?
