 I was a diver for six years and say 90% of the diving I did was not glamorous diving, it was in the Mucky Waters in Norfolk from Virginia Beach down where you can't see anything. So I've had to practice tie-in knots and dragging up things and finding my gear and navigating without being able to see. So it's a direct parallel to what it's like now. And so it wasn't that unfamiliar. The only downside to blindness now is you can't go up to the surface and start seeing it again, but at the same time, this was not the first time that I had to navigate blind. So I was prepared pretty well coincidentally.
