Swearing is not for everyone, of course, but it does have one really big backer: science.
Most jokes about Canadians aren't actually jokes, they're just references to hockey, lumber and/or Rush with the word "eh" thrown in at the end.
I was probably the last person in my school to start swearing. A couple of my friends essentially staged a swearing intervention, refusing to leave until I'd said all of "those" words at least once.
