Sleeping is a primal need. Dancing is a primal need. We don't need to choose between them. We need both.
Some will say sleep is more important, and it is. But dance is also is a human need and a major marker that we are human and not apes (who don't dance spontaneously as humans do). Dancing is a subcategory of the need to move, but a very important and unique need.
But here is the thing--one primal need, sleep, is too often being canceled out for the lesser need and desire of tango.
So here are a few questions for you: Are you still are going to late milongas? Ever heard of the circadian rhythm? Sleep deprivation causing depression? Poor memory? Higher risks for multiple diseases? Lower functioning of the immune system? You probably have. So if you said yes to all these questions, then no doubt you are gently influencing your favorite organizer to make their milonga earlier. Right?
