Between the ages of 36 and 38, I spent nearly $50,000 to freeze 70 eggs in the hope that they would help me have a family in my mid-40s, when my natural fertility is gone. For this baby insurance, I obliterated my savings and used up the money my parents had set aside for a wedding. It was the best investment I ever made. In RAH's 1963 Novel "Podkayne of Mars", the common ability of a woman to "Freeze" embryos in order to delay childbirth is the starting plot generator.
