I am in my sixties. I married a woman seven years older than myself. She died. Then I married a woman six years older than I. I had known her years before, though. Now, suppose she dies (I don't believe in either divorce or breaking anyone's heart) and I want to see if I might still have a chance for a biped family too. I'd have to pair up with a woman at least half my age, wouldn't I? Or do I deserve to be just another Geppetto who never had a chance to have a family of his own?
