Random Survival - An experiment into humanity

What would you do if you were offered the chance to take part in a 5 to 10 year long psychological study, into the habits of humans? How about if there was a sizeable monetary incentive once the study was completed? Sam is a guy who had a pretty rough life growing up, so when he heard about this once in a lifetime opportunity he was eager to take part in it. The only problem is that sometimes you need to read the fine print, before jumping into a new situation, especially a psychological study that no one knows the details about aside from the cash payout at the end. It can't be too hard to get through the experiment and reap the rewards, right?
