Case? Does it matter that much? It's not like asking someone what they would do if they could fly. That's much easier since I have a list of things I would do if I could fly and only one of them is become a superhero.
For all we know I get involved in some weird experiment that goes totally wrong and kills all the plant life on the planet and have to come up with a way to replenish it. Which is sort of boring if you think about it.
