Me and my mate Charlie are planning to do what we call an Iron Age Man. Cycle over a 100 miles, swim then marathon running - the Iron Man distances - but do that with no digital technology. He thinks a polaroid camera counts as Iron Age tech but I disagree. Anyway, the aim is to get better at making decisions under uncertainty. Just the way a natural scientist uses a microscope or a telescope to study things normal perception can't access a social scientist must exaggerate the experience they are studying by living it in an extreme form. I study decision-making under uncertainty. Not knowing the way an still going forward is a good experiment with an N of 1... or 2 in this case. I am forever grateful to Charlie who is willing to try anything with me
