The SAD syndrome is a real thing humans get from the weather.

悲傷綜合症是人類會因天氣而真的患上的東西。

Every time the weather is grey, rainy, snowy, or cold, people clinically feel sad.

每當天氣陰暗、多雨、下雪或寒冷，人們在臨床上會感到悲傷。

People feel depressed.

人們會感到鬱悶。

- It's cold!　- That is the sad syndrome: Seasonal Affective Disorder.

- 好冷！- 這就是所謂的悲傷綜合症：季節性情緒失調。

And I get sad all the time from the changing of the seasons.

我一直在為季節的變化而傷心。

That's why 5 years ago, I made a decision to only wear T-shirts, and to only make videos in places with warm weather.

所以在五年前，我做了只穿 T 恤，且只在天氣溫暖的地方拍影片的決定。

For example, in the month of December, I spent it in Abu Dhabi, the Emirates, where the weather is exactly the right amount for my T-shirt.

例如，我在阿聯酋的 Abu Dhabi 度過 12 月，那裡的天氣正好適合我的 T 恤。

At 24 latitude and 54 longitude for six months every year, the Sun and the Earth are aligned to create the perfect temperature in this part of Pplanet Earth.

在緯度 24 度及經度 54 度的地方，每年為期半年的時間，太陽和地球會呈一直線，並在地球的這一部分產生完美的氣溫。

26 Celsius degrees on average, 1 degree above room temperature.

平均攝氏 26 度，比室溫高 1 度。

So instead of freezing in New York with minus 10 degrees, in this part of Planet Earth, the weather is actually good in the winter.

所以，相較於凍在零下十度的紐約，在地球的這個區域中，冬天的天氣其實很好。

The only rain you will see is this.

你唯一會看到的雨是這個。

OK.

好啦。

I did lie.

我其實撒謊了。

It does get really cold in here, but only before sunrise, because for the rest of the day, the sun is out and the weather is warm again.

這裡確實會變冷，但是只有在日出之前，因為在一天中其餘的時間裡，太陽升起天氣再次暖和。

Scientifically speaking, what makes people happy is not just friends and not just family.

從科學的角度來說，讓人快樂的不僅僅是朋友，也不僅僅是家人。

It's also rays of the sun that are full of Vitamin D.

還有充滿維生素 D 的陽光。

But honestly, temperature doesn't matter.

但說實話，溫度並不重要。

It's the dryness that matters.

重要的是乾燥度。

Abu Dhabi desert weather is dry, which means water evaporates really fast and so does your sweat.

Abu Dhabi 沙漠的氣候是乾燥的，這意味著水分蒸發得非常快，你的汗水也是如此，

So you can spend the whole time in the middle of the desert at noon without any fear of sweating or smelling.

所以你就算整個中午都待在沙漠中，也不用害怕汗流浹背或有味道。

I love the weather, it's perfect.

我喜歡這樣的天氣，它很完美。

It's perfect.

很完美。

We all say happiness comes from the inside, and that's true.

我們都說幸福發自於內心，這是真的。

But happiness also comes from the outside, and the weather affects our happiness and sadness more than we think.

但幸福也來自於外在，而天氣影響我們的喜怒哀樂比我們想象中的要大。

Good weather can make you happy.

好天氣可以讓你快樂。

Bad weather can make you sad.

糟糕的天氣會讓你傷心。

And if that's the case, find yourself a weather that makes you happy.

如果是這樣的話，就去找一個會讓你開心的天氣！
