LEARN A LANGUAGE TO STAY YOUNG

Being fluent in two languages, particularly from childhood, enhances cognitives skills and might also protect agains the onset of dementia and other age-related cognitive decline.
One reason for this could be that speaking a second language builds more connections between neurons. Studies show bilingual adults have denser grey matter, especiallyin the part of the brain where language and communication skill are controlled. The increased density was not pronounced in people who learned a second language before the age of five.
