Why does the brain stop developing after your mid-20s?

Also, what does it mean when people say the brain is fully developed? Does for example learning a new language become harder after your brain ‘stopped growing’?

Short answer is that it doesn’t, it’s just that most of the connections that are needed for you to survive have been made so less development is needed. However, brain plasticity (the brain re-wiring itself, changing in response to experiences) happens throughout life to a greater or lesser degree depending on how much ‘mental exercise’ you do.
