年龄老大不小了却喜欢孩子的游戏，喜欢参加的活动也幼稚的不要不要的。怎么看都不像正常的成年人？其实他们是“返青春”一族。

Rejuvenile is an adult who enjoys activities and items normally associated with children.
“返青春”一族指的是喜欢玩儿孩子的游戏和物品的成年人。

According to Noxon, 36, rejuveniles are people who have “tastes or mind-sets that are traditionally associated with people younger than themselves.”
36岁的诺克森说，“返青春”一族的品味和思维方式更类似比自己年轻的人。

“Most of my days were spent playing Legos with my kids or watching old ”H.R. Pufnstuf“ videos and having a good time in a way that I knew my own parents found pretty ridiculous,” he said.
他说：“大多数时间我都和孩子们一起拼乐高，或者观看旧时的电影H.R. Pufnstuf，我知道我的父母会觉得我的娱乐方式太可笑了”。

例句： Mom is at a pajama party. Dad is organizing a rock, paper, scissors tournament. Will they ever grow up and start behaving like adults or are they part of a new breed of “rejuveniles?”
妈妈在参加睡衣派对，爸爸在组织一场石头剪刀布的比赛。他们会长大，开始像个大人一样做事吗？还是说他们就属于“返青春”一族？
