How much thought have you given to the child that may or may not happen at what age-35, 40, 45……………. They may have a better chance of being healthier but they will loose their parent/s younger, you will not be able to keep up with their energized pace of life, you may not have the patience that a younger woman has when they are young. I really don’t think anyone should deliberately have a child after 40 at the latest. My daughter had my granddaughter at 34 and she thought that was too late.
Not everything should be done just because it can.
