I think I've probably re-invented myself three or four times now, if that's what one calls it.

I've always been involved with all aspects of my careers. Being behind the camera seems as natural as in front.

I do quite a lot of flying in my concerts.

I've wanted to go to space, really, since I was a little girl.

I just wanted a change. My hair started hurting my back, so I went to my hairdresser and said 'Take it off.' And I'm delighted with the results.

I am not a composer of music; I sing pieces which have been written for me which gives me bigger freedom to search for pieces I want to record.

It's in everyone's best interest to help close the gender gap in the sciences.
