What changes does the human body and brain go through between the ages of 18 and 25 ?

I'm 22 currently and feel like a totally different person in the same body compared to who I was at 18.

How exactly has my body and mind changed so far and what changes will I go through next as I heard you stop developing at 25 and then you just age.

I think the most dramatic development that occurs in the brain during this time is in the prefrontal cortex, which is responsible for decision making, planning, and inhibiting emotional impulses. In adolescence, the relationship between the prefrontal cortex and the ventral striatum (which drives exploratory and sensation seeking behavior) is imbalanced, leading to a lack of inhibitory control. As the prefrontal cortex finishes developing, it allows for "top-down" modulation, where the prefrontal cortex can properly regulate those emotional impulses.
