I've danced recreationally for about 18 years, also occasionally teaching, performing, or competing, but I found nothing familiar in this article. I imagine it might also be discouraging for many people to be informed by someone portrayed as a scientific authority that dancing ability is determined at birth.<p>To keep it topical for HN, there is one thing I would say qualifies as a dance hack, although it sounds like a cliche, which is good posture. It should maintained not just while dancing but from the moment one enters the room. Although it's emphasized mainly in ballroom dance, it applies to any form. It works because we read it subliminally as a high status behavior, and faking it won't occur to the people who could most benefit by it.
