“dance, dance, otherwise we are lost”--Pina Bausch

I used to like to dance. Pina Bausch had it right perhaps. Dance or we are lost. She had something to do with Rite of Spring ballet. Rite of Spring ends with the death of a dancer, a sacrifice of sorts. The ballet caused a near riot in Paris when it opened there 100 years ago.
So dance...
What do we sacrifice when we don't keep moving?
Physically, we lose our flexibility. Emotionally our life stagnates.
So what do we do?
Dance.
