Ok, then tell me: what's the age limit? I'm 27, and she has far more experience than I do. It's okay if I wanted to try it, I assume. I could go through the same steps as her, survival training, outfitting a boat, all the experience leading up to this, and nobody would have anything to say about it.
Everyone is certainly entitled to their opinions on this, but as far as I can tell, the only "idiocy" going on here is the vitriolic rhetoric of the detractors.
