For four glorious years straddling the 1980s and 1990s, a TV show aired called Quantum Leap. The premise of the show was that the protagonist, Sam Beckett, would jump through time by "leaping" into other people's bodies. He was constrained: he could only leap into other times that were within his own lifetime. He didn't have control of the leaping, but there was some purpose to it: in each "possessed" body, he had to right some wrong or make some positive change before he could leap again. FOCUS: If you were Sam Beckett and could travel to an earlier point in time WITHIN YOUR OWN LIFETIME, what event would you change, and why? This could be something huge and historical, or it could be something personal. RULE: Like Sam Beckett, you are also constrained: you are NOT allowed to change the same event as any other poster above you.
