Science article

I read a really cool science article the other day. It was about a kid who got into a car accident and had a brain damage. When he woke up at the hospital, he spoke fluent spanish when he had no idea how to speak it before the injury. He was fluent in English ever since being a young kid. This isn't the first time that this incident happened and I thought it was very cool how our brain can be injured and cause humans to speak another language. Which made me think that maybe we are all capable of speaking another language whether we know it or not which doesn't make too much sense but it surely is proven to be true with science.
