Josh has been pushing himself to the limits pretty much all of his life. He's been a British commando, worked in bomb disposal in the Australian army, a stand-up comedian, then a Mars One astronaut candidate and most recently a cave diver, and in all of that, he's been avidly writing about his experiences. I met him back in 2014 while I was embarking on my own space quest and we've remained friend ever since. Brutally honest in all his dealings, Josh seeks out extremes of living, and when mastered, moves on the next challenge. He lives a life that is unique to him and his priorities, which is to be commended. At his core, he is artist and explorer with a keen desire to help others, even at the mercy of his own well-being. His second self-published book 'Cosmic Nomad' launched Sept 17th.
