What age are children’s brains fully developed?

25The age your brain matures at everything — it isn’t even fully developed until age 25. Neuroscientists are confirming what car rental places already figured out — the brain doesn’t fully mature until age 25.

Reality: Even in heavy drinkers, alcohol consumption doesn’t kill brain cells. It does, however, damage the ends of neurons, called dendrites, which makes it difficult for neurons to relay messages to one another.
