I'm going to take you on a deep dive.

I had just returned from one of the deepest dives I'd ever made at that time, a little over 200 feet and, I had caught this little fish here.

And I actually got certified in a pool at a YMCA in the dead of winter in Buffalo, New York.

Since my my first dive in a deep diving submersible, when I went down and turned out the lights and saw the fireworks displays, I've been a bioluminescence junky.

It took me a year to learn to walk again after my diving accident in Palau.

The expansion of settlements in the occupied Palestinian territory and the destruction of basic infrastructure had plunged millions of Palestinians into abject poverty, sharpening tensions and exacerbating the difficulties with which they had to contend.

It took me a year to learn how to walk again after I had my diving accident in Palau and during that year I spent a lot of time learning about the physics and physiology of diving and figuring out how to overcome these limitations.
