Well, I should have known that a simple question would turn into a lively discussion on this forum. It was hijacked in many directions, but at least a few were willing to say how old they were when they started learning Argentine tango: UKDancer was about 50, DChester 49, Anda Bien 43 as I was, Alexandra Weis is the youngest at 15, Sixela was 23, Bastet was about 30, and Twnkltoz was 38. All except one were too old to learn choreography which is often too difficult and too demanding for an adult body, unless trained in dance or similar discipline. The young couples who teach can't relate to a person 60 years old nor should they bother learning the choreography for exhibition. Another question -- if you knew then what you know now about the dance and the music, would you have taken a different path in your experience? What advice would you offer to an adult interested in learning tango as a first dance?
