You shared a picture a while back and you didn't look Indonesian at all. No offense, lol. Also, I gotta go explore Indonesia. 

I'm not so sure its genetics. I mean, everything is genetics ultimately, but I think environment is the main thing and environment (includinh diet) determines how the genetics are expressed. Maybe if we keep eating GMO shit, we'll turn into grey aliens, without our DNA even changing. Seems plausible enough..
