Chilling Trivia and Astonishing Truths That Will Give You the Creeps (1–10)
Even small amounts of alcohol can cause brain shrinkage.
Some people may not drink to the point of getting drunk, but do so habitually and try to limit their intake for their health.
For such people, this is a particularly shocking finding: even small amounts of alcohol can cause the brain to shrink.
The paper describes the brains of people who drink one can of beer a day and states that, although slight, brain atrophy was observed.
The fact that the atrophy is not visible to the naked eye is somewhat reassuring, but since atrophy is indeed present, it seems wise to be even more mindful of alcohol consumption.
A sneeze can travel at over 100 kilometers per hour.
It’s surprising how fast it is, right? Some say it’s not just 100 km/h, but an average of 320 km/h.
320 km/h—that’s the same speed as a Shinkansen bullet train! Knowing this, you can see why wearing a mask when you have a cold or covering your mouth when you sneeze is necessary.
There are more germs on a smartphone than on a toilet seat.
We use our smartphones a lot in daily life, don’t we? Many people check emails and social media in the morning and watch videos during the day.
You’ve probably heard the bit of trivia that smartphones can harbor more germs than a toilet seat.
We use our hands and fingers to operate them, of course.
Hands that touch various surfaces may pick up viruses or even sweat and nasal mucus from people who are ill.
When you then handle your phone with those hands, the sebum and sweat on your skin can cause bacteria to multiply even more.
Try wiping your phone regularly with a cleaning cloth designed for smartphones as a preventive measure.
Sitting too much can be a factor that shortens your lifespan.
How much of your day do you spend sitting? Believe it or not, sitting too much can actually shorten your lifespan.
That’s because it lowers muscle metabolism and raises the risk of obesity and diabetes.
Research also shows that excessive sitting can negatively affect mental health.
Going forward, let’s be mindful of our bodies and consciously increase the time we spend not sitting.
By the way, even if you sit a lot, getting adequate exercise seems to prevent the harmful effects on your body.
If you work a desk job, make sure to carve out time for exercise to balance it out.
In the pinky promise, “genman” means hitting with a fist ten thousand times.
あなたの地域で、あの指切りの歌の歌詞はどうなっていますか?こうした小さな歌や言い回しは「まじない言葉」や「唱え言葉」と呼ばれます。東京のある地域では「指切り、かまきり、嘘ついたら地獄の釜にストンと落とす」と言います。一般的な「指切りげんまん」の「げんまん」は「拳万」と書き、約束を破ったら一万回殴るという意味です。
Whether it’s being forced to swallow a thousand needles or getting beaten, terrible things happen if you lie.
By the way, although the pinky is standard for pinky swears in Japan, in Vietnam they use the index finger.
Different places, different customs.
You might end up eating spiders while you sleep.
This is a bit of trivia that’s hard to prevent and suggests that unexpected things might happen while you’re asleep.
People breathe differently during sleep, and some may sleep with their mouths open.
Considering that, there’s a theory that you might unknowingly eat spiders while sleeping.
Thinking about the reflex when something enters your mouth makes the idea hard to completely dismiss and leaves an unpleasant feeling.
There’s even an urban legend that people swallow more than ten spiders in their lifetime, but it’s only about the possibility—it’s just saying you might be eating them.
Drinking more than 3 liters of water in a day can lead to water intoxication.
We often hear that it’s especially important to stay well-hydrated during the hot summer months when we sweat more.
Here’s a bit of trivia that seems to warn about the dangers of doing the exact opposite—taking in excessive amounts of water.
It explains that drinking a large quantity of water at once can cause symptoms of water intoxication, such as nausea and headaches, which occur when the sodium concentration in the blood drops.
As a general guideline, water intoxication may result from consuming more than 3 liters of fluids in a day or drinking more than 1 liter of water in a short period.
It also teaches that the main problem is not merely excessive fluid intake but the decline in sodium levels, so it’s important to be mindful of appropriate salt intake and the proper elimination of excess fluids.
