Taking flamenco classes is leading to another interesting by-product. It exercises the brain. You need to concentrate, remember the steps and sequences, and think of another dozen things at the same time (hands, elbows, position of chin, heel-toe or toe-heel or both at the same time or interchanged, knees bent or straight, the music, tummy in or hips loose, shoulders low yet sometimes high and so on). I had been considering buying Nintendo's braintraining as I had become convinced that I was suffering from memory loss. But this may well do the trick. Throw in a little kurkuma and I'll be quoting Sartre way past the age of 80.
