my mum's dad, wanted to retire as he 60, but was not allowed as he could not verify his age, as he only had his army records, that just said he declared he was 15 on joining, he had never gone home since he was 14, so he returned to the church near where he born, to collect a birth certificate, only to find that his mother still lived in the same house he was born, he had not seen her since he was 14, the funny thing was that he was actually a year older than he thought, though he got his pension back dated
