hmm... Topic seems almost a "no-brainer" which is intended to be a "pun" making light of the following information.
Part of human development is the evolution between the Limbic "primative" brain; and "Pre-Frontal Cortex".
The Limbic region places no moral value or judgements; it only understands whether something's pleasurable or needed. So for example; ever try to get a three year old to share their toys?
Brain development continues through the mid-twenties; with most wrapping up around 27. By that time, people are generally at a whole different space. Often those who may have struggled with higher education during their late teens/early twenties. Can surprise themselves by successfully resuming such pursuits at a later stage in life.
