From the war on drugs to gay marriage to file sharing, it seems like the law is in a continual, often losing, battle to keep up with the modern world.

Your medicine cabinet will need to be walk-in though.
And We'll Need New Laws Because...
Feel free to take this out of context if we ever run for office later, but we sort of need people to die. Our entire society and economy depends on it, and at some point we'd have no choice but to impose a lifespan cap.
