All look same?

Last week, I did an online test to see if I could accurately identify people who are Chinese, Japanese, and Korean. I'm sad to say I only correctly identified 6 out of 18 of the people. My brother got 10 out of 18 correct. The overall average is 7. I'm actually pretty embarassed by how poorly I did. In a world that's becoming more global by the moment, it's unfortunate that I'm not more culturally aware or more proficient in other languages. I suppose I could devote a bunch of time to improving in this area but it's all a balancing act - and, honestly, right now this isn't a priority for me. But it is important to acknowledge it's a deficiency and potential blind-spot for the future. Hopefully others in my life can balance this out for me.
