The only limit is the one you set yourself.

I always feel the danger because you might always be subject to an unexpected or emergency event.

If something goes wrong, the only thing that might help you is God.

I don't like to rate myself; others can do that. I've spoken with a number of young people who weren't even born in 1969, when the first moon landing was made. They've witnessed the first person to fly at faster than speed of the sound without propulsion. These kids are happy to have had such a momentous event in their lifetime.

Extreme sport has only ever been about goals and the ways to achieve these goals. Adrenaline plays a part, but it's never in the foreground.

To jump and break the sound barrier will not be a mere record breaking experience or another extreme event that ends once the mission is accomplished.

The only limit is the one you set yourself.
