Majority of Canadians are fat, but we never see super fat people like in the USA.

The USA is so massive it has a big amount of super fat people, big amount of skinny, and so on. You won't find that in Canada, everyone here is kinda fat and dopey.

At least in the USA you have a tiny amount of extremely intelligent people keeping the country going. In Canada all the smart people eventually leave to the USA. So everyone here is almost equally dumb.
