It's not about weight, it's about fitness, and one component of being fit is to have relatively low body fat, because fat is not very efficient, whereas muscle is.
Body language is a very powerful tool. We had body language before we had speech, and apparently, 80% of what you understand in a conversation is read through the body, not the words.
At the moment I'm enjoying a new challenge at the Royal Opera House, but I'm also keen to pursue my interest in television and particularly in science.
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 always recommend a sensible diet, including lots of carbohydrates and avoiding too much fat. Dancers don't need different fuel from other people - they just need more of it because they use more energy.
I get to the theatre in plenty of time; I prepare my shoes in advance; I eat and drink the right things at the right time. The rest you have to leave to luck!
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.
It's another myth that dancing distorts or destroys your feet. If you have the right shaped foot to start and a good, strong technique, your feet should be fine.
People often argue about this. Obviously one of the skills in performance is acting, and you can't expect every Romeo to really be in love with their Juliet!
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.
