00:00:00.513 --> 00:00:04.687
You know, it's sad but true, as we get older our brain function starts to decrease.
有件事雖然令人難過但也非常真實——當我們年歲漸長，大腦功能也開始退化。

2
00:00:05.029 --> 00:00:08.913
[You] have more memory loss. It's harder to think clearly. You have cognitive decline.
你愈來愈常忘東忘西，腦筋也越來越不清楚，你出現知能減退的症狀，

3
00:00:09.398 --> 00:00:12.858
And being in a city, living in a city, can compound all that.
而在城市中生活會讓這些狀況更為惡化。

4
00:00:13.734 --> 00:00:16.126
Life in the concrete jungle, that's what they call it,
這是在所謂水泥叢林中的生活。

5
00:00:16.126 --> 00:00:19.076
and if you live in a city, you're probably used to something like this.
如果你住在城市裡，或許你會對這些事情習以為常。

6
00:00:19.474 --> 00:00:24.825
[The] problem is, with so many different distractions, it's very hard to focus on one particular thing.
問題是，有這麼多令你分心的事，你很難專注於某件特定的事物上。

7
00:00:25.052 --> 00:00:28.705
It's called controlled perception, toggling back and forth between so many things,
這稱為控制感知，思緒在這麼多事物中來回拉扯，

8
00:00:29.002 --> 00:00:31.273
and it can leave you feeling mentally exhausted.
這樣會使你感到精神耗弱。

9
00:00:31.798 --> 00:00:34.628
There's no question that living in a city has a lot of advantages.
毫無疑問地，居住在城市中有許多優點。

10
00:00:34.933 --> 00:00:40.260
I mean, shops can be open all hours of the day. You can buy things. There're also lots of cultural attractions.
我指的是，店家全天營業，你可以購物， 還有很多文化景點。

11
00:00:40.515 --> 00:00:44.327
What we're finding more and more is that all of that comes with a price.
而我們愈發了解的是，這些好處都是有代價的，對大腦也有所衝擊。

12
00:00:44.327 --> 00:00:48.909
And there's an impact on the brain as well. In fact, here in Japan, it's a big topic of discussion.
事實上，這在日本是個廣受討論的一大話題。

13
00:00:49.314 --> 00:00:53.054
We're talking about the fact that mental illness is one of the biggest health problems here,
我們談的是個實際狀況，精神疾病是這裡最大的健康問題之一。

14
00:00:53.498 --> 00:00:56.762
and they attribute it to this complex, high-tech environment.
他們將之歸咎於複雜的高科技環境。

15
00:00:57.012 --> 00:01:00.787
Suicide rate here in Japan, no secret, is among the highest in the world.
眾所周知，日本的自殺率在全世界數一數二。

16
00:01:01.121 --> 00:01:04.370
And the thing is that more people live in cities than ever before,
重點是，現在居住在城市的人口比以往都多，

17
00:01:04.370 --> 00:01:08.646
and they're living in cities longer than ever. So, all of this is expected to get worse.
而他們在城市生活的時間也比以往更長。所以這些危機預期都將每況愈下。

18
00:01:08.895 --> 00:01:14.576
And here's why: all that stimulation, well, it can cause spikes to the stress hormone known as cortisol.
原因如下：所有的刺激都會使稱為皮質醇的壓力荷爾蒙急遽增加，

19
00:01:14.933 --> 00:01:18.277
And as a result, it can be very difficult for the brain to hold things in memory,
結果會造成大腦難以留存記憶，

20
00:01:18.716 --> 00:01:24.493
reduce your self-control, dull your thinking. It may even speed up cognitive decline,
降低自我控制能力，使思慮鈍化。

21
00:01:24.856 --> 00:01:29.581
just from living in a city. Think of it as your brain more rapidly aging.
光是住在城市中就能加速知能減退，也就是你的大腦會更快老化。

22
00:01:31.914 --> 00:01:33.392
But here's the part I like in all this --
不過，以下就是我喜歡的部分了。

23
00:01:33.576 --> 00:01:39.279
getting away from the stress associated with the chaos of the big city can be as simple as finding a place like this.
遠離大城市煩亂造成的壓力，其實就如同找個像這樣的地方那麼簡單。

24
00:01:39.361 --> 00:01:46.451
In fact, recent studies have shown just glimpses of green areas can make a huge difference in your overall cognitive function.
事實上，最近的研究顯示，只要短暫目視綠色區域就能對你的整體感知功能造成重大的影響。

25
00:01:46.797 --> 00:01:50.001
It makes you less distracted, less stressed and more relaxed.
它會讓你比較不容易分心，減輕壓力並且有助於放鬆。

26
00:01:50.299 --> 00:01:55.766
In fact, just a few minutes away from bustling Kobe, Japan, we found this place. It's a very old park.
其實距離喧囂的日本神戶幾分鐘的路程，我們就找到這個地方。這是個很古老的公園。

27
00:01:55.766 --> 00:01:57.676
A lot of people come here for a few minutes a day.
很多人每天來這裡待上幾分鐘。

28
00:01:58.009 --> 00:02:01.495
There are shrines, and there are good opportunities to find green space.
這裡有神社，還有很多機會能接近綠色空間。

29
00:02:01.642 --> 00:02:07.800
And that really seems to be the key: find green spaces in your city and make sure to use them as much as possible.
而這似乎真的就是關鍵所在——在你的城市裡找到綠色空間，並盡可能地多加利用吧。
