Maybe it’s because the authors gathered research papers on all types of electric toothbrushes?

In my experience, the difference between manual and electric toothbrushes is huge. I’m no longer nervous about visiting my dentist.

It’s not a comics, it’s a Soviet type propaganda.

After going with a sonic toothbrush, I felt my teeth were actually clean. Much cleaner than before.

Ah, communism is like unicorns. Many people like them but nobody have seen them alive. Because every communist state is not communist but authoritarian.

Just drink sigle origin coffee from a good roaster. It’s much better.

So-called “dictatorship of proletariat” was simply a terror. Lots of philosophers and religious elite was killed just because they weren’t compatible with communist ideology. Rich peasants who didn’t even use others labor were either robbed or killed. Peasants lost their land and had to work for the country. People got killed just because some anonyms told they did something bad. I know this because it happened to my ancestors. My grand-grandfather lost his house, communists left only one room for his family. His friends, all good people, dissapeared. His daughters never played with neighbor’s kids because of fear. My other grand-grandfather lost land and two horses. His brother was killed for not agreeing to give away his house. And my another grand-grandfather was killed because an anonymous letter. He was communist and thought he was safe as he did nothing wrong. His kids couldn’t get education because they were “children of the enemy of the people”. Much later my grandfather got a paper concluding that execution of his father was a mistake. It was horrible time, and lots of people thought the ones who were killed were “pests” or “enemies of the people”, so killing them was good and beneficial for the society.
