and you know your age...or do you?

你還知道自己的年齡… 還是不知道？

VSAUCE! Mic-Woops!

VSAUCE！喔歐！

Nope! Wrong channel!

搞錯了！不是那個頻道！

Hey, there! Welcome to Life Noggin!

大家好！歡迎來到《生活金頭腦》！

Psst, You can get turned into a Life Noggin character... Seriously!

欸欸，你知道你可以變成生活金頭腦中的角色嗎？我沒開玩笑！

Are you sure you know how old you are?

你確定你知道自己多大了嗎？

I can trace my origin back to the exact moment the Creator made me, March 23rd 2013 at 5:27pm,

我的可以追溯到作者創造我的確切時刻，2013 年 3 月 23 日，下午 5:27 分。

and, of course, I incubated for year until my dad decided this whole idea wasn't stupid.

當然，我是在那之後一年，我爸發現這個想法其實不蠢才正式出生的。

But figuring out your true age is a lot more complicated for you humans.

但對你們人類來說，想弄清自己真實年齡比這複雜得多。

There's your chronological age, which is how long you've been alive for and what you use for birthday celebrations.

這是你的真實年齡，你活了多久，也就是你用來慶祝生日的日子。

But there's also your biological age, which is how old your body and cells actually are.

但還有你的生物年齡，也就是你的身體和細胞實際上有多老。

This reflects your health and can indicate your life expectancy, but it's more difficult to determine.

這反映了你的健康狀況，顯示你的預期壽命，但這確認起來很困難。

Biological age is a measure of how fast you're aging by taking into account age-related changes and damages that accrue inside your body as you get older.

生理年齡是透過測量身體「隨著年齡增長而產生的變化及損傷」來衡量你的衰老速度。

The more changes and damages, the older your biological age.

變化和損傷程度越大，生理年齡就越大。

Your biological age can be similar to your chronological age or remarkably different.

你的生理年齡可能與實際年齡相仿，也可能差距甚大。

It depends on aspects of your lifestyle, like diet, stress, exercise and sleeping habits, and living environment.

這取決於你的生活方式，如飲食、壓力、運動、睡眠習慣和生活環境。

I realize that if you're a teenager almost all of those are bad.

而如果你是個青少年，這些生活習慣想必都很差。

But, In order to find out your biological age, scientists use biological markers, which are often referred to as biomarkers.

但為了測出生理年齡，科學家們會使用生理上的標記，通常稱為生物標記。

Triangle Bob, stop sniffing the biomarkers!

三角形鮑勃，不要再聞生物標記了！

Biomarkers are any characteristic of the body that you can measure, like blood pressure or the results of an x-ray.

生物標記代表所有可以測量的身理特徵，如血壓或 X 光檢查結果。

But there are certain ones related to the different processes that occur as you get older that scientists can use to determine someone's biological age.

但的確有些隨著年齡增長而出現的特徵是科學家可以用來確定生理年齡的。

One of them is telomere length.

其中一個是端粒長度。

Telomeres are found at the ends of your chromosomes, but each time the cell divides, they shorten.

端粒位於染色體的末端，但每次細胞分裂時，它們都會縮短。

So an older cell has much shorter telomeres than a brand new one.

所以老細胞端粒會比新細胞端粒短得多。

But this can be difficult to measure.

但這可能很難測量。

Another age-related biomarker is DNA methylation, also known as your epigenetic clock.

另一個與年齡相關的生物標記是 DNA 甲基化，也稱為表觀遺傳時鐘。

While a genetic change alters your DNA and affects what chemicals your genes produce,

雖然是基因變化會改變 DNA ，影響基因產生的化學物質，

an epigenetic change determines whether or not a gene is turned on.

但表觀遺傳變化會決定一個基因開啟與否。

This can be caused by your lifestyle.

這會受你的生活方式影響。

One way epigenetic changes happen is by DNA methylation.

其中一種表觀遺傳變化 DNA 甲基化。

This is a process where methyl molecules are added to your DNA, which turns the genes on or off.

這是將甲基分子加入 DNA 中，從而打開或關閉基因的過程。

As you age, certain genes become methylated that would be better off not,

隨著年齡增長，某些不要甲基化比較好的基因就會甲基化，

while other genes lose their methyl groups that would be better suited with them.

而另外一些則會很可惜的失去甲基。

This results in things like gray hair, wrinkles, and joint pain.

這導致了諸如白髮、皺紋和關節疼痛等問題。

Everything a 30 year old looks forward to!

都是 30 歲的人最期待的東西！

Studies have found that patterns of DNA methylation, 

研究發現，DNA 甲基化的模式

which can be measured from a blood sample,

可以透過血液樣本測出，

accurately predicted chronological age.

這能準確測出年齡。

And many researchers and companies have used this method to develop their own epigenetic clock or wellness test

許多研究人員及公司已經使用這種方法開發了自己的表觀遺傳時鐘或健康測試，

where you can discover exactly how old you are.

讓你可以準確了解自己的年齡。

At the very least, it could be an excuse to have another party!

至少，這可以成為多舉辦一個派對的藉口！

Happy 2,785th birthday, Triangle Bob!

2,785 歲生日快樂，三角形鮑勃！

His body's been through a lot!

他的身體簡直傷痕累累！

So, my question to you, the beautiful person watching, how old do you feel?
