You know fucking what? I like it. Its got charm to it.
First off the bat, all diseases physical, genetic and infection, basically anything not having to do with the mind, is cured. Next, alzheimers patients now get retention of memories, they'll have an average memory. Whether they come back or not is up to them.
Next, no one needs to eat or drink anymore and are made healthy once. (or at least as healthy as they'd be if they ate correctly. Fat people will still have to excersize and skinny people need to eat a lot to become big)
War, as I see it, is a very fucking hard thing to suddenly fix. War isn't just a country fighting, its a set of ideals against another, a country's worth of people wanting to kill another country worth. Then you get into religious reasons, such as the muslim religion condemning gays and unlike christian, its not god's responsibility to take them out, its there's.
We'll just put a bandade on a flesh wound, for the next 24 hours no one will die. Not that anyone CAN'T die, they just WON'T. bullets will miss, bombs will fail, an angry mob will have a change of heart, etc etc.
Now, I create a new world hub, and in the hub is going to be worlds I create. A fantasy world specific to my tastes for starter's. Next I will go to every individual human and ask them 1 wish and to go into a new world I had created.
I won't grant every wish or send everyone to a perfect world, but I'll give everyone in the world a chance. Every single human will get 1 more chance to start fresh or become what they want. Dragon and fantasy world? Done, You'll start as a baby to learn how to be a dragon. You just want to be a female? Done. You don't want to die? What about an afterlife with viewing power instead?
The last thing I'll do is leave an afterlife for everyone. They'll go to the hub and get to pick a new world to be reborn into, I'll add to it and leave a search mechanism in it for people to find a specific world.
And then I'll retire.
