It is ticking. It's the life cycle. We feel young at heart and love our child. But age counts. It counts the years.
Young parents can also die or deteriorate.
But we are talking odds. There's no reason to cheer the biotechnology that allows the goose to do what nature neglected to prevent the gander from doing. I don't see how we can legally ban elder women from getting eggs. But we can insist that human eggs be allocated as wisely by doctors and donors as livers or kidneys. Not that long ago, women depended on Mother Nature to help make their decisions.
