Until the age around 25 your brain is not fully developed. The exact age varies person to person, but it's around 25
Although brain development is subject to significant individual variation, most experts suggest that the brain is fully developed by age 25. For some people, brain development may be complete prior to age 25, while for others it may end after age 25.The mid-20s or â25â is just an average age given as checkpoint for when the brain has likely become mature.hese days, a consensus of neuroscientists agree that brain development likely persists until at least the mid-20s â possibly until the 30s. The fact that our brains arenât developed until the mid 20s means that âlegal adultsâ (those age 18+) are allowed to make adult decisions, without fully mature brains.
