One theory from a neurological perspective is that every single time you have a new experience, your brain is firing and using and creating more neurons so that it can record as much detail as possible.

從神經學的角度來看，有一個理論是，每當你有新的體驗時，你的大腦都在發射和使用並創造更多的神經元，以便它能儘可能多地記錄細節。

Think about a hike when you first are walking on a hike, it always feels like it is taking longer.

想想看，當你第一次在徒步旅行時，總是感覺花的時間比較長。

Then when you turn around and walk back the way you came.

然後當你轉身走回你來時的路。

That's because when you're walking back it is no longer novel and therefore it goes by faster.

這是因為當你走回去的時候，它不再是新奇的，是以它走得更快。

And as you age, you have fewer truly new experiences.

而且隨著年齡的增長，你真正的新經驗越來越少。

And this lack of stimulation has been shown to speed up your perception of time.

而這種缺乏刺激的情況已被證明會加速你對時間的感知。

Speaking of new experiences, we're about to have a wild one because for Earth Day 2022 Youtube is sending us on a mystery trip so we can appreciate the beauty of earth and we get to share it with you.

說到新的體驗，我們即將有一個瘋狂的體驗，因為在2022年地球日，Youtube將送我們去進行一次神祕的旅行，這樣我們就可以欣賞到地球的美麗，我們也可以和你們分享。

And it's all part of their non fungible planet campaign, which is celebrating this one of a kind planet we call home, but we literally don't know where they're sending us yet.

這都是他們的 "不可替代的星球 "活動的一部分，該活動是為了慶祝我們稱之為家園的這個獨一無二的星球，但我們實際上還不知道他們要把我們送到哪裡。

So you can help us guess could it be the Rocky Mountains?

所以你可以幫我們猜測一下，會不會是洛基山脈？
