Because I can...
You're stranded on a desert island. It's just you. You have no electricity so you can't bring any electronics. The papers from all books must got to your campfire. You are allowed ONE item (not paper or electronic). What is that item that you'd bring?
Think Tom Hank's Wilson (one of my least favorite movies btw).
I'd bring a pocketknife because I'd hope it'd be useful. Anyone ever read the hatchet?
