During the last dancing weekend we had a heat burst in town and all the dancers were dripping of sweat. It happens to each and everyone so it is socially ok, we really don't mind anymore. Somewhere during the weekend I stopped to mind about myself too; I stopped to monitor how the drops were advancing along my neck, my back. I just focused on music and my partner.
During the weekend I woke up without any stiffness or pain in my body. I reflected it but became aware of the difference after the first ordinary milonga. The next morning I could not just jump out of the bed but carefully went up and with slight stretching get the body going and start the day. It was as usual again.
Those hot milongas kept me painless!
