I am surprised he didn't mention once asking the locals. That is my key to knowing how people live in different countries. Also you get tons of inside information and it is an easy step to connect to people. Often times you get 'adopted'. You find yourself as a special guest on a private family garden party. Or on parties in locations that only the 'cool people' know it is open because Corona regulations mixed things up.

I am currently recording hundreds of videos to share all knowledge on YT.
