The experiences of being a teenager are deep and lasting — first break-ups, fierce arguments with parents, that time a friend tried to skateboard off the roof. Why is that time of life experienced so intensely and remembered so vividly?

Dessa finds that many answers lie in neuroanatomy and the way our brain wires itself as we grow. She meets teens and a brain scientist to find out why the rollercoaster highs and lows of teenage life might be good for us in ways adults just don’t get.

Deeply Human is a BBC World Service and American Public Media coproduction with iHeartMedia.
