Six decades have passed since Jackie Bassett first appeared on TV aged seven, skipping down the road with her little sister.
It was 1964 and she had been selected by teachers at her east London primary school to appear in a documentary called 7 Up.
The show interviewed 14 seven-year-olds from vastly different socioeconomic backgrounds. Inspired by the Jesuit saying: "Give me the child until he is seven and I will show you the man", it was intended as a one-off - a snapshot of Britain's class system and how it shapes us from a young age.
"They only picked me because I never stopped talking," Jackie told the BBC, with an infectious giggle that hasn't changed since childhood.
Little did she know then, but Jackie was being filmed for a show that would go on to be the longest-running documentary series ever made. In 2024, it was voted the most influential TV show of the past 50 years.
Now the curtain is falling, with the final instalment - 70 Up - airing on ITV this Tuesday.
