In the year 2000, PostNord delivered nearly 1.5 billion letters. Last year, it delivered 110 million.

Makes sense when you really think about it. U.S. letter mail is mostly junk.

Canada post office has a standard letter being no more than 50g.

So 5.5 mil kg. That is a lot to carry.

I would hate it bc it makes the apps that companies make more enticing; which makes data collecting more profittable. So yeah.
