The air is free
There is one of those stereotype jokes that goes why do Jews have big noses and the answer, ba rum bum, is the air is free. Similarly, I was reading this book T got me called Lazarus and it is a Bosnian author who writes about how when he gets together with his immigrant Bosnian friends they always talk about how Americans are crazy the way they go outside with wet hair or open the windows and let the draft come in – all which cause brain damage. Similarly, I was speaking to a friend who was saying how nice it is right now with the windows open and she said she doesn’t understand how the Italians chop their necks complaining of drafts or how the French have parties with everyone smoking and the window is barely cracked.
Nature and nurture.
