It's amazing how today's modern research and brain imaging technology shows how multilingualism actually strengthens the brain. In an article published by Mindshift accompanied by the video below by Lisa LaBracio for Ted-Ed, we learn that people who speak more than one language actually have a higher density of gray matter that contains most of the brains neurons and synapses.

The study also compares the differences between learning a new language as a child vs. adult. 

Scientists hypothesize that adults tend to acquire a new language using their left brain, so they approach problems in a more rational, detached way. The benefits of learning a new language are endless and it's indeed refreshing to be reminded that we are starting our kids out with an advantage by teaching them a new language at a young age.
