Star, I do not know if meeting latter in life would had make a difference. Many people meet later in life. It does not prevent a MLC (unless it had already happened) and it does make them that much better dealing with issue in a relashionship.
Of course if one is 45, 50, 60 or more years old, had lived a serious relashionship, let's say, has lievd a spouse MLC, then, yes, I think it can make a huge difference.
