As you get older, the physical abilities decrease, which is particularly frustrating because your brain gets so good! So as you are becoming less technically or physically able, younger dancers are emerging who need the space to perform. ↗
I wrote the song For A Dancer for a friend of mine who died in a fire. He was in the sauna in a house that burned down, so he had no idea anything was going on. It was very sad. ↗
I think it's useful to experience other types of dance and other cultures, and the life of a classical dancer these days is certainly not all tutus! So experience of other dance forms is a good idea. ↗
Young dancers are training at a very vulnerable time in their lives, through adolescence, and while they are trying to work out who they are as people, never mind as a dancer. So train the whole person, not just the dancer. ↗
