The first day I arrived at England, I went shopping for necessities and groceries right after moving into my dorm room. I didn't know my health was totally PROTECTED by the airports and the dorm regulations until the minute I walked in the crowds on the busiest street of our town.
EVERYBODY WAS SMOKING!
Oh my god, I am not kidding or exaggerating. Every British man, no matter male and female, young and old, walking fast or fooling around slowly, everyone passing by me held a cigarette, and I was literally walking in the smoke!
