Now, you may scoff, but after trying it I can honestly say, even though it's quite hard to start with, the sense of achievement is pretty bloody amazing. And great for your posture.
And something to impress the girls with.
Yes, I'm still crap at it. And yes I've impressed no-one so far.
It's easier than learning Spanish, let's face facts - land in Buenos Aires in a few months with pretty poor Spanish coupled with a Scottish twang or........... pretty much zero Spanish, but can dance a bit of tango, enough to get a cheeky smile out of the Porteño - preferably the female population.
It's a no-brainer.
