Body, Mind or Soul?

This question has been raised before, but I would like to pose it all the same.

—–What is the rationale behind setting the 14 year age limit for a person to be considered a child laborer?——

Is it the body which at age 14 is deemed fit to start absorbing the rigors of life while seeking economic sufficiency?

Is it the mind which at age 14 is deemed to have acquired the maturity to make informed decisions about seeking a vocation/career path? In that case how do the laws make accomodations for individuals with limitations in mental abilities to safeguard their rights?


Is it more philosophical where the soul has crossed over into the realm of reality from that of make believe?

———Can this age limit be questioned? How?———
