From the Same Wikipedia article on Jeanne Calment:

In 1965, aged 90, with no living heirs, Jeanne Calment signed a deal, common in France, to sell her condominium apartment en viager to lawyer François Raffray. Raffray, then aged 47, agreed to pay a monthly sum until she died, an agreement sometimes called a “reverse mortgage”. At the time of the deal, the value of the apartment was equal to ten years of payments. Calment lived more than thirty additional years. Raffray died of cancer in December 1995, at the age of 77, leaving his widow to continue the payments for twenty more months.

I’ve only got one wrinkle, and I’m sitting on it.
