Your brain be POWER UP if you study second language?

Can you POWER UP your brain by studying a second language?

私はとにかく何でも調べる事が好きで、
I really like to searching anything,

("searching" or "to search" - どちらかが正しいです。）

何か疑問があったり、はっきりしない事があると、すぐに検索します。
I am on google immediately when I have find things not that don't make sense or are unclear.
（私も！）

私がよく行く言語学習サイトに「５か国語を話せる」というイタリア人女性がいたんですね。
There is an Italian female who can speak 5 languages on the a language learning website that I visit.of the learn languages. (Wow, impressive!)

英語だけでも四苦八苦している私にとっては、神でも見たかのような気分になりました。
Then I felt kind of like I saw a God at her ability, because I am in great trouble even I am just studying a second language, such as English.

（外国語を習うのは難しいですね。）

そこで、ある疑問を持った私は、いつものように「言語を学ぶための特別な能力を持った人がいるのか、いないのか」調べてみました。
So, I tried to research like I usually do usual that about "there are something person types who has have special ability at who's brain or not for studying other languages."
(I'm  not sure how to word this, but I think "Are there people whose brains are naturally better at learning other languages?" or whether it's possible for "just anybody" to learn many languages or if it is a special inborn ability)

頭がいいかどうかは論点に入れず…。だって、私にとってのその答えは、すでに解っているので.笑
(Without to think about who is smart or not. Because I know the answer to me. ^0^).
(Regardless of whether a person is smart or not, because I know the answer in my case.)

And then I found so these interesting articles at below.

"Neurolinguistics: Structural plasticity in the bilingual brain"

Humans have a unique ability to learn more than one language a skill
that is thought to be mediated by functional (rather than structural)
plastic changes in the brain.
Here we show that learning a second language increases the density
of grey matter in the left inferior parietal cortex and that
the degree of structural reorganization in this region is modulated
by the proficiency attained and the age at acquisition. This relation
between grey-matter density and performance may represent
a general principle of brain organization.

BBC "Learning languages 'boosts brain'"
http://news.bbc.co.uk/2/hi/health/3739690.stm
They found learning other languages altered grey matter
the area of the brain which processes information
in the same way exercise builds muscles.

This is very interesting information, and I wonder about this myself. One reason I started to study Japanese was to stretch my brain as I get older. :) Here is a link to a very interesting video (in English) that I found very helpful on the subject of language learning.
