• I never wanted to do TV. I just did what I was trained to do through the Special Forces, and I've been doing that from a very young age.

• My faith isn't very churchy, it's a pretty personal, intimate thing and has been a huge source of strength in moments of life and death.
• As for my diet, I try to eat lean, clean and healthy - nothing too surprising. And I avoid too much meat or dairy because they slow you down.
• I always had a really natural faith as a kid. Where I knew God existed and it felt very free and pretty wild and natural, and it wasn't religious.
• Faith is personal if it's to be real.
• My faith isn't very churchy, it's a pretty personal, intimate thing and has been a huge source of strength in moments of life and death.
