It's time to do another one of our most requested videos.

是時候讓我們來播放許多觀眾要求的影片了。

Here's some more common myths debunked!

我們要來破解普遍存在的迷思！

You excited?

你們興奮嗎？

I'm excited!

我很興奮！

Let's do this!

讓我們開始吧！

Something we've all probably been taught is that our tongues can be broken down into different regions based on taste.

我們最常被教導舌頭可以根據味覺分成不同的區域。

As if we can point to a certain area and say, "there it is! That's the spot that makes cake taste so darn good."

宛如我們可以指著特定的位置說：「就是這裡！就是這個位置讓蛋糕嚐起來特別美味。」

That's clearly wrong.

這完全是錯誤的。

The five tastes can be sensed on all areas of the tongue, especially along the sides.

舌頭任何部位都可以感受到五種味覺，特別是舌頭側邊。

The only thing slightly true about this myth is that the back of our tongue is very sensitive to bitter tastes.

唯一稍微正確的是舌頭根部對於苦味非常敏感。

Next up!

下一個！

Don’t fall prey to the common myth that "bats are blind".

別相信「蝙蝠看不見」這個常見的迷思。

In reality, bats can see perfectly well.

事實上，蝙蝠的視力非常好。

They can also use echolocation to hunt insects at night and map out an area.

牠們也可以用回聲定位在夜晚偵測所在區域，並捕食昆蟲。

So next time you are in a cave for some reason, the bats know you are there and they are watching.

所以下次如果你因為某些原因在洞穴裡時，蝙蝠們知道你就在那裡，並且正注視著你。

Have you ever been told that a penny dropped from the top of a very tall building could kill you?

你有沒有聽說過從很高的大樓掉下的硬幣會砸死你?

This is a lie.

這是個謊言。

Because of air drag, the terminal velocity of a penny is between 30 to 50 miles per hour, or maybe even less if there’s wind.

因為空氣阻力的關係，硬幣的終端速度會介於每小時 30 至 50 哩之間，如果有風的話，速度甚至會更慢。

It might not feel good if it hits you, but it won’t drill through your skull.

雖然被砸到時你不會太好受，但你絕對不會穿透妳的頭蓋骨。

There is also some weird belief that people with red hair are going to go extinct due to climate change.

有奇怪的說法是紅頭髮的人因為氣候變遷而將絕種。

But this is ridiculous, a gene can't just "die out" unless every single person with it suddenly keeled over.

這非常荒唐，除非世上每個有這個基因的人都死光，不然一個基因不會就這麼「滅亡」。

Rather, red hair is a recessive gene, meaning both parents must have it in order for their children to show it.

相反地，紅髮是隱性基因，意思是要生紅髮小孩必須父母雙方都帶有這個基因。

So, it could become more and more rare, but redheads won't be "extinct".

所以，紅髮人可能越來越少，但他們絕對不可能「滅絕」。

To all the gingers watching, we love you and want you to stay around.

致所有的紅髮觀眾，我們愛你，也希望你能長壽。

So, tell me in the comments the myth that bugs you the most and maybe when we do another one of these videos, it'll be featured...hm?

留言告訴我們哪些迷思最讓你苦惱，或許我們會再製作同主題的影片然後再放上來...

Make sure you come back every Monday for a brand new video.

每週一敬請收看我們全新的影片。

My name is Blocko, this has been Life Noggin.

And of course you know what to do but I'm gonna say it anyway!

當然你知道該做什麼，但我還是要再說一次！

Don't forget to keep on thinking!

別忘了要持續思考喔！
