Hi,
I've read this story by Jack Sharkey in German - it is translated as "Die Dämonin" (the female demon). In this short story Bob Terrill notices that he is aging rapidly - even though he's just 36, his dentist tells him that his teeth are at least twice that old. After some suffering Bob discovers that his wife Valerie is sucking away his lifetime. The frail Bob throws his vampiric wife from the balcony. She dies, dissolves to dust and Bob becomes again a middleaged man.

Does anyone knows the bibliographic dates - original title, where and when was it first published?

Thanks in advance.
