Everyone here in Pakistan wears a suicide jacket and carries grenades (at least a dozen) in his pockets. Imagine conditions here. Pakistan is one of the cheapest countries in the world. 
I've friends from UAE. When talking to them I tell them prices of things here, for example a auto mobiles they are shocked. 
Pakistanis are at no 81 among 158 countries with happiest citizens. Which is far better than its neighboring countries like , India, Bangladesh,Iran etc.
Pakistan has no caste ism which also make people happier. You don't have to post an ad on matrimonial websites to search for partners just because of different caste. 
Life in Islamabad is quite similar to the life in any big city of the world.
People are always busy and mostly mind their own business. Law in order, perfect security systems, very low crime rate. For these reasons most of the foriegners prefer to live in Islamabad. I remember a most of people are shifted to Pakistan to seek a safe place out of war zone lives in Islamabad withhis family. Most of the Afghani refugees live in Islamabad..
