Deputy Editor of RAG MUSIC. JFC-certified fact-checker. I’m Sasashina, a mom currently raising an elementary schooler and a preschooler. During my student years at Kyoto College of Science and Technology, I studied a wide range of fields including sound, lighting, and video technology, building a foundation in comprehensive stage production and creative expression. After graduation, I joined a music production company, where I still work, consistently building experience in production and engaging in a variety of music-centered tasks. Currently, I mainly handle articles for children, drawing on what I’ve learned about parenting and what I feel and discover through daily interactions with my kids. I hope my work can be of help to you, even in a small way!

I’ve been playing the Electone since I was six, mainly performing Disney music, anime songs, and music from dramas and films. I post performance videos on YouTube and social media, and I also give concerts. Building on my Electone experience, I took up synthesizer and piano during my student years and performed at school-sponsored events. As a writer, I’ve covered not only music-related topics but a wide range of genres, so I hope to draw on my experience to deliver articles that make readers think, “I want to try that!” or “I want to listen to that!”

Some of it might make a few people regret seeing it a little, but there’s also plenty that’s good to know.

Scary Trivia About Earth, Space, and Life (11–20)

Anisakis won’t die even if you cut it.

Anisakis are parasites that mainly infest seafood, and if accidentally ingested, they can cause severe abdominal pain and nausea.

If you look closely, they’re large enough to be seen with the naked eye, so you might think they’re easy to eliminate.

However, they’re terrifyingly resilient—they can survive even if chewed or cut.

So how should you deal with them? The most effective method is heating: it’s said that heating to 60°C for one minute will kill them.

When eating raw dishes like sashimi, it’s important to choose items that are very fresh and have had their innards removed promptly.

Chilling Trivia and Astonishing Truths That Will Give You the Creeps (1–10)

The creature that has taken the most human lives so far is the mosquito.

When we think of creatures that take human lives, we imagine venomous animals or powerful beasts we can’t overpower.

But the answer is mosquitoes.

It’s surprising that such tiny insects could be responsible, but mosquitoes transmit life-threatening infectious diseases like dengue fever and malaria to people.

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.
