Wearing a mask. In Hogh Kong, if you're even slightly sick, you wear a mask. If you feel ugly, you wear a mask, if you're just lazy, and don't want to do anything - you wear a mask. Most Asian countries actually wear masks, and it's not because we want to, it's because we grew up knowing that as a society, we need to protect each other

I thought this was a normal thing everywhere until my American friends were like "what the [hell], why do you do that? That is so weird".
So we leave our babies outside when they're supposed to sleep. For example, If you're going to a restaurant, there will often be strollers outside with babies sleeping in them. It's normal in most of the Nordic countries. I just thought it was a thing everywhere. And also when they're in kindergarden and it's nap time, you'll just see a bunch of strollers outside. And no they are not cold, they are always packed in the stroller with a bunch of clothes

You go to a store, you purchase a live fish, that you bring home in a plastic bag, and you let it live in your bathtub. Because this kind of fish, it's a karp I believe, and it live in muddy waters. And it's kinda gross, so it needs to cleanse itself in clean water before you can eat it. My family used to do this every year up until a few years ago, and every year, I named the fish Michael. So before people took a shower, we needed to put Michael in a bucket.

In Ireland, we Speak English, so the way you say you say 'no' is 'no', and the way you say 'yes' is 'yes'. However, if you're in your friend's house nad your friend's mom offers you food, 'yes' is then pronounced 'ah, no sure, I'm grand'. To which she'll respond 'ah, you will'. To which you'll respond ah, no honestly'. To which she'll respond 'ah, go on you will'. To which you'll finally respond 'ah, sure, wouldn't say no'. Despite the fact, you've just said 'no' twice, and you've been secretly starving the whole time. It's a linguistic tradition, not the most time efficient, but it is what it is.

However, if you are still not married by the time you turn 30, it's pepper.

Everything has to be translated into at least 3 languages. I live in Switzerland, a small country in the center of Europe with 8.5 million population. There are 4 national languages: German, French, Italian & Rhaeto-Romance. Rhaeto-Romance is spoken by a small part of the population so it's not widely used in businesses. If you have a nation-wide business, your website needs to be translated into at least 3 languages, same with brochures, instructions, product boxes. Sometimes if large companies do a presentation, they will actually do it in 2 languages, or people will receive headphones with a live translation. In some small villages, cinemas will have 3 sets of subtitles, taking up half the screen.

The sheer amount of carbonated beverages that we drink. I've never been to a country where this is a normal standard amount of sugar. Even when I was in Europe, none of the soft drinks were ever this big, this is a purely American thing. And probably for the best, because nobody needs 44oz of coke.

One is for internal use, which is basically an ID card for most countries. But here in Russia, we have many pages of information about our citizens, like who your children are, where are you living, and other things like that. The second passport is an international, Russian Federation passport. And not every Russian has it, you need to pay about $60 to $70 to get one. And all my visas are stored here.

In Sweden, you can just type in the name of the person on Google. The results will come up, his full name, date of birth, where he lives, what car he drives, how much he earns, everything. It's free for everyone to just check, I think that's very unnatural

If you ever visited, you might be surprised to see so many people with red-stained mouths. Well, it's from chewing betel nut. It's a social practice that every Papua New Guinean does. From the elders to the young ones. And there are 2 ways to chew betel nut. You can just crack open the green nut and chew the flesh regularly, or you can dip the dake, which is the green stem, into the kambang, which is a white powder, to produce a red paste in your mouth. And basically, this is a drug, it's a stimulant, it's like coffee, it gives you a burst of energy, people usually chew this in the mornings.

In Argentina, when you graduate university your friends and family attack you with eggs, flour, contiments, oil, food in general, paint, foam, anything. And they just drench you in head to toe as a celebration. The way it works is you let everyone know when your final exam is, and if you pass, you change into comfy clothes and everyone gathers around you and throws stuff at you. In the past few years it has changed from food to paint, foam, confetti, as to not waste food, but a lot of people still do the food thing. So you go with a carton of eggs and just whack them at the person who graduated.

It's very common to see a Brazilian brushing their teeth or flossing in a public bathroom or workplace bathroom. We also take multiple showers a day, usually 2 or 3 showers. And we eat pizza with a fork and a knife, I don't really know of any other country that does this, I'm sure there are, but we eat pizzas with a fork and a knife.
