Love the stories - but quick thought- do you have to be crazy to go?

Loving the stories, but a quick thought was all the people you have interviewed (so far) are just divorced or about to get divorced, have PTSD, or are getting over abuse! These are interesting stories to hear, but If I do the trail I hope there are some people who are not in an ‘unstable emotional state’ or is this a big cause for people to do this type of adventure?
