 Here I am at the firefighters' stand behind me. I'm feeling a little bit of trepidation here. We're doing this interview before I do the climb for obvious reasons, because I might have completely out of breath, but for a fantastic worthwhile cause. There's over 600 firefighters on the climb, and they always support crews and families and loved ones here, and it's about getting the conversation going around mental health and smashing the stigma around post-traumatic stress injury and other mental health issues.
