This striked me, despite 1 is without arm. The other is without leg yet they can combine and dance beautifully. The obstacles that they overcome is more than that of us, normal human people with all limbs. They have to be physically strong and mentally too.
There is this story behind them, seems that the guy lost his leg in an accident. The lady a dancer who lost her arm went to get him to be her partner. As he is not trained before, they faced a lot of rejection to co-ordinate to what you see today. Amazing right?
