In the video the guy presents how little we know about our brain and how it works. He tries to drive a bicycle with reversed steering wheel and it's a no go. But his 6yrs old son learned to do that faster than him. Which means that younger brain has better cognitive plasticity. What took 8 months for him his son did it in few weeks.
Also after he learned to drive reversed bike he had trouble to drive normal one. Which means that we know how to drive our bikes but we don't have understanding of that process.
