Also worth noting: All the countries at the top of the list are basically Socialist.
I guess they haven't run out of other people's money yet.

But the majority of the countries are grouped pretty closely, with scores roughly between 6.75 and 7.0, which makes me wonder what these type of polls are really indicating. It’s hard to fully trust the results, without knowing more about the specific questions they asked to come up with these somewhat unclear scores.

Then I would like to know what significance did they assign to each different category in the poll, as properly weighting them all can be problematic as well.

I'd like to read the original article (or the reports on which the article is based).

Also, are those Appearance scores or Performance scores? Can I just PM the reviewers to ask for more detailed Juicy Details? (Thank goodness there isn't an overabundance of "Once in a lifetime.")

Yes, these are cold places, but that means people spend more time indoors than in more temperate climes.  That's more time to have sex, so why wouldn't everyone be happier there?  It makes perfect sense to me.
