This is not some stray Arab ancestry - Arnab is a throwback to the Central Asian Aryans who invaded India as is Michael Johnson who goes back to Normans, Saxons, Vikings et al.
For some reason - starkly Aryan locking Indians come from Bengal and the brahmins of the South. They must be "sports"
While the AVERAGE looks of paki Punjabis and kashmiri Muslims and Muslims in general is phenomenal - the young Hema malini before her face took on fat (very early and stayed there) is probably the most beautiful Aryan woman who has ever lived.
