Dancing is a tough career, but I'm glad I spent it at the Royal Ballet.

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.

A good dancer is an educated one, so don't abandon school.

I did get a very fine education, and not just in science. It took some pressure on the part of my elders to convince me that I really should take an interest in humanities.

The scientific and scholarly community is marked by the belief that the truth is to be found in all; none can claim it as their monopoly.

Art and science have their meeting point in method.

Sex is a discovery.
