Throughout the course of History, humans have shown a keen interest in testing and overcoming their limits in many different ways. Running ultra-long distances non-stop for several days, venturing into the dangers of the sea on a tiny a sailboat, and floating in zero-gravity inside a tin-can in the void of space are just a few examples of how limits appear as irresistible temptations just waiting to be surpassed.

In our modern society, people are expected to behave according to certain norms. We assume that if one person can do a task well, everyone else should be able to, if they try hard enough. In fact, not all brains are wired the same way! For example, most of our jobs include many tasks that require us to maintain constant focus. While some people have no problems dealing with these aspects of our society, others quickly become disengaged from repetitive tasks and constantly look for new stimulation.
