Being an "old soul" and being an "old person" are two different concepts:
Old Soul: An "old soul" refers to a personality trait or a belief that someone's spirit or consciousness is more mature or experienced than their physical age suggests. It's often used in a metaphysical or spiritual context, and some people believe that old souls have experienced many lifetimes, accumulating wisdom and knowledge throughout those existences. Old souls are often seen as wise, introspective, empathetic, and drawn to profound insights about life and human nature. This concept is more about the depth of one's character, wisdom, and perspective rather than their chronological age.
Old Person: "Old person" is a term used to describe someone who has reached an advanced age in their current lifetime. It is solely based on their chronological age and the number of years they have lived on Earth. As people age, they go through various life experiences, which can also lead to increased wisdom and life lessons. However, being an "old person" is primarily about physical age and the stages of life a person has passed through.
In summary, the key difference is that being an "old soul" is a more abstract and spiritual concept, reflecting someone's perceived maturity and wisdom beyond their years, while being an "old person" is a factual statement about the number of years someone has lived in their current life. It's possible for someone to be an old soul and still be young chronologically, or vice versa, for someone to be an older person but not necessarily possess the qualities associated with an old soul.
