Hey there! Welcome to Life Noggin! It's time to do another one of our most requested videos.
大家好！欢迎来到脑洞大开的生命奇想！应大家的强烈要求，又做了一个视频。
Here's some more common myths debunked! You excited? I'm excited! Let's do this!
又要辟几个常见的谣言。期待吗？反正我期待！开始吧！
Something we've all probably been taught is that our tongues can be "broken down" into different regions based on taste.
我们可能都听说过，舌头可以根据味觉分区。
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."
好像我们可以指着某一个区域说，“就是这儿！就是这里让蛋糕那么好吃的。”
That's clearly wrong. The five tastes can be sensed on all areas of the tongue, especially along the sides.
错！舌头上所有区域都可以感知五味，尤其是舌边。
The only thing slightly true about this myth is that the back of our tongue is very sensitive to bitter tastes.
这个谣言唯一有点对的地方是，舌头后部确实对苦味非常敏感。
Next up!
下一个！
Don't fall prey to the common myth that bats are blind.
蝙蝠看不见东西？可别上当！
In reality, bats can see perfectly well.
其实蝙蝠视力特别好。
They can also use echolocation to hunt insects at night and map out an area.
夜里他们也可以用回声定位来捉小虫子，标注地盘。
So next time you are in a cave for some reason, the bats know you are there…and they are watching.
所以，下次再到洞穴里，要知道蝙蝠知道你在，他们在看着你呢。
Have you ever been told that a penny dropped from the top of a tall building could kill you? This is a lie.
硬币从很高的楼顶掉下来会伤人致死，听说过吧？这也是假的。
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.
在空气阻力的影响下，硬币的自由沉降速度保持在每小时30到50英里，有风的话会更慢。
It might not feel good if it hits you, but it won't drill through your skull.
被打到可能不是很舒服，但也不至于被硬币砸穿头骨。
There is also some weird belief that people with red hair are going to go extinct due to climate change.
还有个奇怪的谣言，说因为气候变化，红头发的人要灭绝了。But this is ridiculous, a gene can't just "die out" unless every single person with it suddenly keeled over.
真是荒唐，基因是不会轻易灭绝的，除非带有这种基因的人都突然被干掉。
Rather, red hair is a recessive gene, meaning both parents must have it in order for their children to show it.
不过，红头发是隐性基因，这意味着父母都是红头发，才能保证孩子是红头发。
So, it could become more and more rare, but redheads won't be extinct.
所以红头发的人才会越来越少，但不会灭绝。
To all the gingers watching, we love you and want you to stay around.
在看视频的红头发们，我们爱你，希望你们永远都在。
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, hmmm.
好了，请在下方评论区告诉我最困扰你的谣言，我们可能会以它为主题做一期视频。
Make sure you come back every Monday for a brand new video.
每周一都要来看新视频哦~
And if you want even more Life Noggin, check out this video we did on the science of cooking.
了解更多生命奇想，还可以观看有关烹饪中的科学那期视频。
Thank you so much for watching! My name is Blocko, this has been Life Noggin,
感谢收看！我是宝高，这里是脑洞大开的生命奇想。
and of course you know what to do but I'm gonna say it anyway! Don't forget to keep on thinking!
接下来我要说什么大家都知道了。思考不要停！
