The real Secret of a long marriage:

My sister, a doctor, told me about one of her patients, a 92-year-old woman who showed up for her appointment with her husband, who is 94. They said they have been married for almost 70 years.

My sister, highly impressed, asked the couple the secret to their union's longevity. And they looked at each other for a long moment. Then the wife spoke:"Eh, neither of us died."
