Hey AG, I bake bread, but please don't fawn all over me for doing it....
Actually, when the cupboards go dry, if you can find a source of, or grow, your own dent corn AKA field corn, you can pretty much survive on it alone, especially if you are capable of hunting to get a little extra in your diet.
Our native American ancestors grew corn, beans, and hunted, and pretty much survived for thousands of years, you only have to look back at them for the pattern to make it.
Good thing this topic wasn't brought up at TOS though, I would have hated to see the OP's inbox for suggesting that anyone over there take a pay cut, let alone what they did to him in the ladies room.
