If I had time to grab only 3 things to survive I would probably grab a big bag full of food and bottled water, a knife, and my warm blanket. I would survive by making myself look like a cave woman, finding where the cavemen live, and living with them. I think it would be much better and safer to live with them rather than trying to make it on my own. I would be hard to understand them, but I'd learn, to not get eaten,but I'd try my best to live. Well that's all I have to say for now, fair winds.
