I think teleportation would be absolutely wonderful, absolutely stunning. If you could transport yourself from one place to another, or you could be transported without the hassle of aeroplanes and waiting for trains, that would be absolutely wonderful.

I'd also like - it's going to sound very strange - but I would love to have had the power once, just once, perhaps a month or two months, to be able to change sex, and to see what it feels like to be a woman. My wife actually feels the same way. She said it would be great for two months. I wouldn't want to stay that way, but just to find out.
