The section mentioning Kim Ham-bo in the Manchu version of the History of Jin

The name of the founder of the Jurchen nation is Shanpu.
tuktan solgo ci jidere de ninju se funceme bihe.
He was 60 years old when he first emerged from Goryeo.
This is the part about Kim Ham-bo in the Manchu version of the History of Jin. It says that at the age of 60, he went to a Jurchen village, married a woman of the same age, and had two sons.
However, while it is possible for a man to father children at 60, it seems nearly impossible unless it's a miracle for a woman to give birth at 60, yet that is how it is recorded in the historical texts.
I wonder if I should actually believe this fact.
The historian who wrote the History of Jin probably had their doubts as well.
