On Languages

Today I learned a fun fact from a friend. A human baby is born able to make roughly 200 sounds, but each language uses only 50 ish sounds. So by the time you learn to speak your native language, you have lost the ability to make the other 150 sounds, making it difficult to later on learn drastically different languages. Don't know if it's 100% factual, so don't quote me on it, but I found it interesting.
