To console myself for a trip I couldn't make to Buenos Aires late last year, I watched this several times because it's at a milonga I'm familiar with, and to remind myself how simple and relaxed the dance there can be. (I get complaints if I embed a video of a dance floor with only one couple on it... can you believe it? After all, a milonga starts with just one couple.) This is Lujos in Salon Plaza Bohemia, last Sunday night I guess, since the clip is very recent: there's Oscar making sure all the tables are just right (it's his milonga), and the familiar waitress taking first orders. I should have been there! From Marina2x4's excellent channel. Thanks!
& something I just read. (A long article, scroll down to the end.) We interpret movement by following it unconsciously with our own muscles, even if we aren't actually moving: thus we come out of a cinema feeling we are walking differently, we've absorbed a way of moving, we can mimic it. Watching dance helps us absorb the movement. Sadly, the reverse is true. A French research paper has recently shown that people who have botox lose some of their facial movement, and accordingly they lose some of their ability to interpret emotions on other people's faces.
