More than six decades after he first expressed his apprehension about marriage, Paul Kligerman, a participant in the long-running Seven Up! documentary series, has revisited his memorable childhood explanation for his reluctance: a fear of being forced to eat green vegetables.

In the inaugural 1964 episode, a seven-year-old Kligerman told producers he was concerned that a future wife would insist he eat foods he disliked. "I don't like… say, you had a wife, they... say, you had to eat what they cooked you and, say, I don't like greens, well I don't, and, say, she said you have to what you give, so I don't like greens… say, she gives me greens… and that's it," he explained.

Kligerman was among 14 children from diverse socioeconomic backgrounds chosen for the Seven Up! series, which has revisited their lives every seven years since its inception.

When viewers first met Kligerman, he was residing in a London children's home following his parents' divorce. By the 1970 installment, '7 Plus Seven,' he had emigrated to Australia with his father and brother. His struggles with confidence and expressing emotions were documented in '21 Up.'

Despite these early challenges, Kligerman met and later married Sue in 1978. The couple went on to have two children. He credits the documentary series with helping to mend his estranged relationship with his mother after he encountered her during filming in the UK.

Over the years, Kligerman has worked in various professions, including as a bricklayer, in a sign-making company, and in maintenance at a retirement village.

Now appearing in the latest installment, '70 Up,' Kligerman is shown as a devoted grandfather, still married to his wife of 48 years. Reflecting on family in the documentary, he stated, "You need a good family. You need it for yourself and you need it to make your life whole." He also shared reflections on his late father, acknowledging his efforts in raising him and their successful father-son relationship.

Kligerman emphasized the importance of kindness and forgiveness, advising, "You have to learn to be kind to other people and forgive them for their failings. Live the best, honest life you can."

'70 Up' is scheduled to air on ITV1 and ITVX.
