I'm generally interested in things such as race so looking into ancestry of Europeans (+ Eurasians, Indo-Europeans), Africans, and Asians (+ Native Indians) contains information that one can always learn something new he or she didn't know previously.
Without going off-topic too much, some Eurasians are more towards being European-looking while others are more towards Asian-looking. Keanu Reeves (I watch any movie he's in) for example looks mostly European, though those who can identify races can tell he's partially Asian.
Maria Ozawa also looks mostly European (I don't remember how I came across her name, just keep in mind she does "adult" "acting") and Carlos Ghosn (European-Japanese) too, but Ghosn can look either part whenever he wants.
Moreover, without looking up info on Jair Bolsonaro I knew he was of German ancestry based on his looks. Yes, Wikipedia states he has Italian roots has well, but the German side seems to be the majority of his DNA.
P.S. Westerners (Europeans) tend to treat people who live in the Americas differently, except most of them share the same DNA/ancestry so they shouldn't hate (yes, even to that point). Hell, regardless of race, really. No need for anyone to be xenophobic or racist, it feels as though most of the time it happens out of ignorance (Mr. Brown from The Office was right!
).
