Can a friend translate this text from Turkish into good English, please?

As you know well, Turkish and English are different cultures. Translation is a very important and difficult process.

"Bugün dünyada 7 milyarı aşkın insan yaşıyor. her nsanın, genetik, toplumsal, kültürel ve kişisel kültürü farklıdır. Her insan, bu sosyolojik olguya göre düşünür, davranır ve konuşur. Her insan, bu sosyolojik olguya göre duygu ve düşüncelerini ifade eder.

Bu konuda, Türkçede güzel bir deyiş vardır : "Her insan ayrı bir sima -yüz- ve ayrı bir fikirdir."

my attempt for the first part:

More than 7 billion people live in the world today.

Every person has different genetic, social, cultural and personal characteristics.

(The direct translation would be personal cultures, but this sounds strange to me. Characteristics = özellikler)

Every person will think, behave and talk according to this sociological reality.

Every person will express their feelings and thoughts according to this sociological reality.

Turkish has a wonderful saying on this subject:

Every person has a different face and a different opinion.

(This sounds better in English to me, because you can use ´different´ both times, but ´separate´ and ´individual´ and ´distinct´ don´t fit as simply in my opinion)

thank you very much
