That's the ticket!
No too sure what to say about this, seems men can make baby's at 90 years old , Woman now with technology can incubate a baby from their grand child. Freeze sperm and 30 years later when the old fart dies and disowns you, divorces you for good reason, get pregnant , have his baby and claim part of his estate.
Don't have to have a sex life any more, just get that sperm frozen and pop up with a direct heir to confuse and gain a share of an estate and knock out the heirs born naturally.
Interesting world we are moving into. The legal and moral ramifications of all this. Much harm has been done to children caught up in the system, poor kids, a great injustice done to them.
What the heck , I loved SCIFIE books as a kid but today I am smack dab in the middle of the middle of one of the plots written some time 50 years ago.
