The product of two years of foreign language courses among high school graduates, is less than a graduate student, fluent in the language studied (Caplan). Being bilingual has been shown to have many benefits that enhance not only a student's educational life, but also how the person can be shaped and cultivated in everyday life. It has also been proven to result in some diseases disappearing more slowly. It can also strengthen the mind, allowing one to think more effectively. If it turns out that there are benefits to bilingualism, the school district, the students' parents, and the students themselves should be concerned about the benefits of bilingualism. The public must be made aware of all the advantages of bilingualism for the child's future. EvenHe talks about a study by Tamer Gollan, a neuropsychologist at the University of California, San Diego. He carried out a study on 44 Spanish-English bilingual elderly people. Gollan measured the level of bilingualism in each subject. The results showed that a higher level of proficiency in two languages ​​led to a lower occurrence of certain diseases (Bhattacharjee). In the article “The Power of the Bilingual Mind,” by Jeffrey Kluger, he talks about a study done by Ellen Bialystok. In this study, she studied older adults suffering from “severe age-related cognitive decline.” She found that bilinguals gained 4.1 more years of clarity before dementia symptoms appeared. She also found that bilinguals gained 5.1 more years than monolinguals who developed Alzheimer's disease. specifically (Kluger). If put into perspective, being bilingual does not completely stop or prevent these diseases, but being fluent in two or more languages ​​shows help in the onset of the disease with the help of other medications to help. Simply put, research shows that being bilingual helps prevent these diseases but will not prevent them.
