I semi-seriously believe that you should get more votes if you’re younger, or a more heavily weighted vote, based on the average expected number of decades you have left to live. Like, e.g., an eighteen year-old ought to live for roughly another six decades, so their vote should be weighted to take that into account. And I say this as a thirty-[mumble] year-old! Eighteen year-olds should have more of a say than I do, because they’re going to be affected by the decisions made now for much longer than I am.
