I'd make sure that everyone who wants to lose weight would be able to, while eating all the junk they are addicted to.
And alcohol wouldn't have any calories or give hangovers.
And i wouldn't send coded messages open to vast interpretation. And if I were "God" with all the power inherent in running the universe, I'd be sure not to let people slaughter each other in my name.
That is, if I had that kind of power.
