You’ve got to keep trying because you don’t know what amazing things are round the corner. Also, always be grateful – at one point you wished to be where you are today.

It occurred to me that at one point it was like I had two diseases – one was Alzheimer's and the other was knowing I had Alzheimer's. There were times when I thought I'd have been much happier not knowing, just accepting that I'd lost brain cells and one day they'd probably grow back or whatever. It is better to know, though, and better for it to be known, because it has got people talking, which I rather think was what I had in mind.

Always have final cut

You’re going to come up against brick walls in life. You’ve got to go over them, under them, around them, or crash through them, but somehow or other you’ve got to get to the other side.

Natural, caring, thoughtful.

Not being honest.

Heights, and not getting along with people.

Lack of confidence in speaking to the opposite sex.

Being about nine metres away from a polar bear. In northern Canada, a young polar bear was very intrigued by our food. I was flying the drone at the time and the polar bear looked up and started paying attention, so then we flew the drone further away and he followed it while we got into our vehicles.

There’s a tweet somewhere saying, “If you like Africa so much, why don’t you go back there.” It was because I dedicated one of my dances to my three mothers – Mother Africa, Mother Nature and my mother.
