The risk of putting all my grades in a single system was the potential for that system to fail. And, yet, the reward of keeping grades and papers in a computer is that I don't have to write by hand! Doing risk analysis is fundamental to computer science, but it should be easy to do in any aspect of our lives.

We have an idea of how to describe risks, select some activity of your life that is NOT directly computer related but that can be seen to be not-entirely-safe, and share the risks, rewards, and safety protocols/practices you employ in that activity.
