I would build a massive network of treehouses

First of all it depends on whether everyone else knew this was going to happen or not, because I could handle the knowledge and accept death, but I really feel that most people could not and therefore would totally freak out and there would be widespread chaos- either then the government would go into a crackdown state or it would just be total anarchy- but since this is only a hypothetical question i will answer in that fashion - thinking that things would not get too bad and i could still carry on a somewhat normal life.

I also, like jack posted down below, would live fairly close to how i do now- spend time with friends and family, i would probably stop playing video games though, but would probably not work out as much and drink/smoke more, but other than that i would stay in college.. and if everyone left college then i would head home and build a massive network of treehouses in the woods next to my house and have all my friends live there with me in the woods with nature.
