My brother was 17 and he went to join up and he had to be 18, so he wanted Dad to sign him away. And Dad said, "I'm not signing you away."
He said, "Well if you don't sign me away, I'll go under an assumed name." And Dad said "You're not going under an assumed name. If anything happens to you, we won't know."
So, he said, "If I sign you away, I sign myself away." So, Dad joined the Second AIF. And he was over in the Middle East. He put his age back seven years to get in. That's where the determination comes from.
