I cannot believe that you think that women can give birth at 50+. It is very very risky. If I could only go into the gory details of labour I would give you an idea. Do you have any idea how painful it is and will the 60 year old be able to withstand the pain?

Miss doctors themselves strongly advise against IVF after 50 and most dont do it. Until you get a special court order.
One day I would like to meet all you women and tell you the facts of life. Till then I am KnoxCollege.
