Learning a new language offers numerous cognitive benefits, including delaying dementia, enhancing listening skills, and improving memory recall. Bilingual individuals exhibit greater cognitive flexibility, allowing for improved multitasking and sharper focus. Overall, the advantages of being bilingual significantly outweigh any previous misconceptions about language learning.

1. Why we should learn a new language
Charlemagne once said, "To have another language is to possess
another soul. » Another soul?
Somehow this celebration of learning second languages was not
always the case; it was once more recently thought that learning a
second language was a sign of dual personality disorder or could
onset schizophrenia and other disorders.
This was thought to be true because many who were bilingual had
smaller vocabularies and slower access to sentence structure.
However, in today's day and age the cons of knowing more than one
language are far outweighed by the prose.

2. Better Listening.
Listening skills are heightened in those who are bilingual. Once
someone speaks more than one language, they can hear different
sounds and tones and recognize them, thus creating a subconscious
analytical mindset. Babies who grow up in bilingual households can
distinguish and differentiate languages they've never even heard
before.

2. 3. Better Memory Recall.
Those same babies who grew up in bilingual households also show a
stronger memory recall. Their memories were also recalled with more
clarity and accuracy this leads to faster learning, especially in math
and a better recollection of faces and names which allows creating
stronger relationships at a much quicker rate.

4. Multitasking.
Despite the fact that multitasking is impossible as our brains are only
capable of tackling one thing at a time, rapid task changes are vastly
improved by being bilingual. Because being bilingual requires
cognitive flexibility, allowing the speaker to be able to shift from one
task to the next much quicker and with more ease than those who
only speak one language.

5. Sharper Focus.
Bilingual people also have both languages activated in their brains at
the same time, monitoring which is appropriate for which given
situation, which can improve attention and focus. Learning another
language can also shed new perspectives on different topics:
Dancy Susilo conducted a study in June 2015 that showed that those
who are bilingual had higher abilities to process information and their
self-perception was different.
