Why Ken Okoth And Wife had three adopted children and non of their own

Ken Okoth passed on yesterday. Most Kenyans were keen to know more about the family.
Ken Okoth had married a white woman from Germany.The couple are blessed with three children .All of them were adopted.
You may wondering why! The main reason is that Ken Okoth wife is much older than him.
When he married her,she had already passed the age where a woman could conceive naturally.
That explains why they adopted the children.
Nevertheless they are loving and caring parents.
