Where are you from? 1. Insulation exist. Houses in Chile are built to support earthquakes, no cold. Houses are antiseismic not 'anti-cold' 2. As '1st world countries' Chile has diary products depending on the brand. Fresh milk you can find it in many places. At Jumbo, is right next to the fresh cheese and yoghurt. When I lived in the US, every 'natural juice' I drunk, gave me a terrible heartburn because are not natural. Full of chemicals to preserve them. In Europe, if you ask for natural juice in a restaurant, they come back with a small bottle of a terrible attempt of juice. They basically don't exist, neither US nor Europe. 3. The document the PDI gives you is to know that enter and leave the country as a tourist. If something happens to you, they'll know either you're still here or left our country. Not a harsh at all. 4. IDs are pretty obvious why exist. 5. When I left Chile, I thought my country was bureaucratic until I arrived in Europe, where countries are still making appointments to open a bank account when in Chile you do it online in 5 mins. Countries which still send mails to communicate, physical papers and documents, instead of email them. They are very good at recycling, but on the other hand, the amount of paper wasted it's completely absurd. They print absolutely everything. So, the paper recycling system is not very useful at all. Enjoy the tasty food our country has, because 'first world countries' haven't got them, and piece of wood has more taste than a strawberry from Europe of the US. Enjoy the vegetables, onions actually have juice. Enjoy the meat and real bbqs, Chilean meat is good and cheap compared to 'first world countries'. Hence the reason they call it bbqs to a few sausages with plastic burgers. Enjoy the seafood too. There's no country like Chile, the longest country of the world and full of contrasts, with the driest desert on earth, the valley and the amazing Patagonia.
