A 21 year old "Elder"...just the person to trust with important life issues.
Most medical journals agree that males don't fully develop their frontal lobe until the age of 25...and some not until 30 years of age. Most insurance company stats back this up noting that risky driving habits wane after the 24th birthday...and their rates usually reflect this. Under 25, young males are easier to manipulate...therefore easy targets for cults, cons, and the military to mold. ( It's easy to see Watchtower's angle here).
Quote: "It doesn’t matter how smart teens are or how well they scored on the SAT or ACT. Good judgment isn’t something they can excel in, at least not yet.
The rational part of a teen’s brain isn’t fully developed and won’t be until age 25 or so.
"In fact, recent research has found that adult and teen brains work differently. Adults think with the prefrontal cortex, the brain’s rational part. This is the part of the brain that responds to situations with good judgment and an awareness of long-term consequences. Teens process information with the amygdala. This is the emotional part.
In teens' brains, the connections between the emotional part of the brain and the decision-making center are still developing—and not always at the same rate. That’s why when teens have overwhelming emotional input, they can’t explain later what they were thinking. They weren’t thinking as much as they were feeling." end quote. https://www.urmc.rochester.edu/encyclopedia/content?ContentID=3051&ContentTypeID=1
