The brain is usually not considered to be like a muscle, but it is actually the same as any other part of the body. Just like the muscles in your arms or legs, it will get weaker without regular exercise. Research has shown that learning new languages later in life has some very important benefits. One of the most significant benefits is related to how the brain keeps the new language information it learned. For younger people all the information about a new language seems to be stored in just one part of the brain. But for people whose brains are already developed, the new language information is kept in several different areas of the brain. This means that more of the brain is being used and exercised.
