Ben Sansum is 35. But he lives in 1946.
His clothes, his house, the music he listens to - all come from an era before he was even born.
He has always been interested the 1940s, but it is an interest that has grown over the years. He's gone from buying reproduction furniture for his house to tracking down the real thing. His 70-year-old carpet is his latest pride and joy.
BBC News went to meet Ben at home in Cambridgeshire.
