Babies at 60

I just heard on the news tonight about a woman that had a set of twin babies at 60 years of age. This was a medical miracle and I am awaiting the full story on this but it sounds as though she had the babies implanted. Is 60 too old to be having babies, that was the question posed at this point but really if you are a person that is full of love and in fair health why not allow them to have children.
