There is, and always has been, a lot of strife in the world related to how people perceive "nationality" and "other". This moving video suggests that perhaps there might be less strife in only we all knew the nationalities of our ancestors via DNA testing.
It's a great sentiment, though while widespread DNA testing might help with our collective perspective around race and nationality, it comes with a raft of other ethical issues as well. (One of my favourite movies of all time, Gattaca, deals with just one potential scenario.) Personally, I think an easier way to achieve such perspective is simply to travel. It's a suprise that wasn't the message of the film above, given that it was sponsored by a travel website, but there you go.
That's all from us this week. See you back here on Monday, and have a great weekend!
