Sounds horrible, but I'm game for zombies.
Not in the way of losing pretty much every single iota of sustained technology (besides dams and reactors etc) as well as TOTAL BUTTFUCK ANARCHY
but
It'd be a fun way to live out the dying star that would be the Human race, should it happen.
Plus, a lack of conflict when zambies (besides the moral issue of whether or not to beat the un-living life out of a corpse, should it even be a corpse...)
