second childhood

The concept of "second childhood" is often associated with the idiom "come of age." While "come of age" typically refers to the transition from adolescence to adulthood, it can also describe a later stage in life where individuals experience a rediscovery of their childlike qualities. This is similar to the idea of a second childhood, where adults embrace a carefree and playful mindset, free from the responsibilities of adulthood.

The idiom "grow up" is often used to encourage someone to mature and assume adult responsibilities. In contrast, the idiom "grow out of" suggests the natural progression of individuals out of certain behaviors or stages. When someone experiences a second childhood, they may temporarily "grow out of" their adult mindset and revert to a more childlike state of being. This can manifest in various ways, including a renewed sense of wonder, spontaneity, or playfulness.

Lastly, the phrase "over the hill" is another idiom commonly associated with the concept of second childhood. "Over the hill" is often used humorously to describe people who have reached a certain age where they may romantically reminisce about their youthful days while also embracing a carefree and fun-loving outlook. This aligns with the notion of second childhood, as it highlights a period of life where individuals embrace their inner child while reflecting on their past experiences.
