Why Kashmiris so good looking?

We had to watch this documentary in geography lesson and kashmiri people look so beautiful very light skin chiseled yet very soft features, in fact I would love to marry a kashmiri girl, They were Muslim people so I was wondering could they be rememnents of muslim invaders, such as ottomans, or even persian invaders cuz they look different to most other indians, more afghanistani, why is this?
