simple idiot apocalypse scenario

In just few days, the world was hit by a highly contagious virus that degenerated people's intelligence. People forgot how to drive, how to calculate, and even worse, how to speak. The social infrastructure is gradually crumbling, factories are shut down, and the streets are filled with wandering people. Only you, and only you, are immune to this virus. How will you handle this situation? Will you create a cure and become a hero, or will you reign supreme over a bunch of idiots? (Or just walk into any house and fuck helpless people lol). +v2 I made peoples dum more. +v3 I was dum.
