Once you've hypnotised someone once, you can pretty much put them under instantly any time you meet them afterwards.

I'm not saying I do evil things. I'm just saying if a cop stops me when I'm speeding, sometimes - not all the time - I might get out of that ticket. Let's just say I don't have any points on my licence in Ireland, and I drive relatively quickly.

Hypnosis is about shutting down the conscious mind and re-igniting the unconscious and the imagination, so while I give instructions to them under hypnosis, the contestants might interpret those instructions in all kinds of ways.

In 2006, when doing a live stage show in Ireland, I tried for the first time to instantly induct a subject on stage, something I had never done before, nor did I know if it would ever work. The result almost cost me my career; the man I grabbed and instantly inducted went out cold and fell to the floor.

I am constantly asked can anyone be hypnotized, and does it really work? Yes, and it does.

I have to stay in shape for the physical endeavour stunts I do. I work out a lot. I have a personal trainer. I go two or three times a week. I'm on a diet where I photograph everything I eat and send it to her.
