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.

I do take class because I still dance, and yes, I do slip into class with the Royal Ballet from time to time.

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.

But you do have to start young as a dancer if you're going to achieve the physical skills necessary.

Because muscle is heavier than fat, dancers weigh more than you might think, but they are usually very lean.

So if the dance is five minutes long, make yourself run for perhaps eight minutes. That way, you over-train and the dance will seem easier.

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.
