back in time

I'm home alone asleep, when I wake up I'm being transported back in time to the cavemen age. I need to quickly grab three things out of my house before I get lost in time. I hurry and grab a picture of me with my family, a health kit in a back pack filled with bottles of water, and a book of things I can eat. I would survive because I watched the hunger games last summer. I'll have my medicine for when I have injuries, my picture so when I'm down I'll see my family no matter what, and the book so I'll know what i can eat and what I can't.
