In the inaugural episode of the long-running documentary series Seven Up!, a seven-year-old Paul Kligerman expressed a peculiar fear about marriage: the prospect of being forced to eat green vegetables. This memorable moment, captured in 1964, has resurfaced as Kligerman appears in the show's latest installment, '70 Up.'

During his first appearance, Kligerman explained his apprehension to producers. "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," he stated. "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."

Kligerman was among 14 children from diverse socio-economic backgrounds chosen for the Seven Up! project, which has revisited them every seven years since its inception. At seven years old, he was living in a London children's home. His relocation to Australia with his father and brother occurred before the 1970 follow-up, '7 Plus Seven,' when he was 14.

In '21 Up,' Kligerman spoke about his struggles with confidence and expressing emotions. However, by that time, he was dating Sue, whom he would later marry in 1978. The couple went on to have two children, as documented in '28 Up.' Kligerman credits the series with helping him to reconnect with his estranged mother after seeing her during filming in the UK.

Over the decades, Kligerman has worked in various professions, including bricklaying, sign-making, and maintenance at a retirement village. Now, in '70 Up,' he is portrayed as a devoted grandfather, still married to Sue after 48 years. He reflects on the importance of family, stating, "You need a good family. You need it for yourself and you need it to make your life whole."

Kligerman also shared his thoughts on his late father, who passed away about ten years prior. "He brought us up and was a good man. He did the best he did and, as far as I'm concerned, he did a good job," Kligerman said. He added a broader life philosophy: "You have to learn to be kind to other people and forgive them for their failings. Live the best, honest life you can. The happier your family is, the more it spreads out and just keeps getting bigger."

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