The biological rate of maturation of the human brain hasn't changed appreciably in the past 200 years. People were given a full range of adult responsibilities at a young age in the past, but that doesn't change the reality that a 22 year old and a 13 year old have a VERY serious power imbalance based on their brain's maturation thus far.
