Ronaldo is from Portugal.... its the latin blood, they all have really thick black hair and Too much of it really, like one poster already said, in some Latin guys and even women you cant tell where the hair strarts and their eyebrows end...
check some latin women out, J-lo for example... very very hairy..
northern europeans, your british, your irish, germans, scandavians, ect... have a less hairy forheads, and i think more likley to go bald. there are acceptions... for example Steven Gerrad, he is a typical British Lad, but an unusually low hairline that would normall see on a Latin guy like ronadlo.... see below....
