The hardest thing about my job isn't the snake bites or the crocodiles, it's being away from my children. I have a really religious satellite phone call every day back to the boys, wherever we are, whatever time zone, to say goodnight.

Juice Plus+ is great stuff that I have used through all of my expeditions. What I like about it is that the research behind it is so strong. It is 100% natural, is whole food based, and I love the fact that it provides raw, anti-oxidant fruit and veg in a capsule form. For me it fulfills a key part of my nutrition, training and recovery needs.
