Eww!
2
What is that smell?
3
It's awful!
4
Oops!
5
It ate too much cheese!
6
Ugh!
7
I wish I could lose my sense of smell just for a while!
8
Then what?
9
Hmm, you know, that's actually a great question, little kitty.
10
So, let's dive into that mystery to answer, what if you lost your sense of smell?
11
Zoom in!
12
Imagine waking up one day and realizing the scent of pancakes, the earthly aroma of rain,
13
or even the stink of gym socks is completely gone.
14
That's life with anosmia, a condition where you lose your sense of smell.
15
But before exploring this scentless world, let's first understand how smelling works.
16
You see, everything around us releases tiny molecules into the air.
17
These molecules eventually enter our nostrils,
18
where the nasal cavity works to filter out dust and other particles.
19
At the very back of your nose lies the olfactory epithelium,
20
a small but crucial batch of tissue, packed with specialized neurons called olfactory receptor cells,
21
which act like scent detectives.
22
When an odor molecule reaches this area,
23
it dissolves in a layer of mucus and binds to the receptor cells that get activated.
24
This causes them to send electrical signals through the olfactory nerve via the olfactory bulb and along the olfactory tract.
25
These signals are then processed in different regions of your brain including the amygdala,
26
thalamus and orbitofrontal cortex where they are interpreted as specific smell.
27
This direct connection explains why smells can instantly trigger memories,
28
emotions or even your fight-or-flight response.
29
Now you might think of smell as just a bonus sense.
30
Nice to have but not essential.
31
In reality it's critical to many aspects of life.
32
For starters, smell works hand in hand and with taste to create the flavors you enjoy.
33
Without it, your favorite foods would taste flat and uninteresting, like chewing on flavorless cardboard.
34
Beyond taste, smell alerts you to dangers like smoke from a fire, a gas leak or spoiled food.
35
So, without it, you'd need to rely on alarms, expiration dates or sheer luck to avoid trouble.
36
Speaking of which, for various reasons,
37
this crucial sense can become impaired or lost altogether in a condition called anosmia.
38
Yes, anosmia can be caused by something as simple as a cold or allergies,
39
which block scent molecules from reaching your olfactory neurons.
40
Most serious causes include brain injuries,
41
neurological conditions like Alzheimer's or Parkinson's disease or congenital anosmia,
42
being born without a sense of smell.
43
Aging, smoking and certain medications can also reduce your ability to detect odors.
44
When you lose this vital sense, it can make everyday life more difficult.
45
You'd miss out on small joys like the smell of fresh flowers or your favorite meal.
46
Worse, you might not notice spoiled food or milk, increasing the risk of food poisoning.
47
You might also fail to detect dangers like smoke in your home or workplace Or exposure to gas or harmful chemicals.
48
The good news, most cases of anosmia are temporary.
49
Treating the underlying cause such as clearing a sinus infection often restores your ability to smell.
50
However, for some the loss can be permanent.
51
So, make sure to protect your sense of smell by avoiding smoking
52
and maintaining overall health to lower the risk of colds or infections.
53
Next time you can catch a whiff of rain,
54
cookies or pine, take a moment to appreciate this incredible system.
55
Trivia Time!
56
Did you know about thousand people in the United States have congenital anosmia?
57
Also a dog's olfactory epithelium is 20 times larger than that of a human.
58
To know more check out our nostalgic video on dogs.
59
Sketching time!
60
Today's sketch of the day goes to Mira Kulbe.
61
Hope you discovered something crucial today.
62
Until next time, it's me, Dr. Binox, Zooming out!
63
Never mind!

このレッスンについて

このレッスンでは、嗅覚を失う「アノスミア」という状態について学びます。具体的には、嗅覚がどのように機能し、アノスミアが日常生活に与える影響について理解を深めます。視覚的なイメージを持ちながら、YouTubeで英語学習を進め、アノスミアに関連する語彙と表現を使って会話練習を行います。

重要な語彙とフレーズ

  • アノスミア (anosmia) - 嗅覚を失う状態
  • 嗅覚 (sense of smell) - 匂いを感じる能力
  • 嗅覚上皮 (olfactory epithelium) - 嗅細胞が存在する鼻の部分
  • 匂い分子 (odor molecules) - 空気中に存在し、匂いを作る物質
  • 脳 (brain) - 嗅覚の信号を処理する器官
  • 思い出 (memory) - 匂いが引き起こす感情や記憶
  • 危険 (dangers) - 煙やガス漏れのような危険を知らせる感覚
  • 喪失 (loss) - 嗅覚が失われること

練習のコツ

この動画のスピードやトーンに合わせて、shadowspeakを実践することが大切です。まずは動画を数回観て、話されている内容や発音に慣れましょう。次に、メモを取りながら音声を聞き、重要な部分を反復します。その後、音声に合わせて発声しながら、英語スピーキング練習を行ってください。この方法で、英語の発音を良くする実践的な練習ができます。特に感情や強調を意識しながら声に出すことで、自然な会話力が身につきます。最後に、動画を観ながら自分の声を録音し、後で聞き返してみると、さらなる改善点が見つかるかもしれません。これを通じて、嗅覚の重要性についての理解も深まります！

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
