denmark isnt the happiest.at least what i hear form one of my danish friend. i will go for switzerland. wow i was there. that place is heaven on earth. they earn more money than americans, living standard is higher than even americans, country almost one fourth of the size of nepal. talk about many international organizations and you will find headquarters in switzerland. country despite being rich has always maintained its neautral instance in war. thats why it is so peaceful and never comes to news like US and Britain who have to poke their nose in every war to come to news. all the student studying in UK do visit switzerland and you know what you even dont need eu visa and british visa is good enough.2 days 2 nights £150 pound is more than euough.
