Like most sensible people, I spend a good deal of time thinking about how I would survive if thrown into the past with just the clothes I had on. I probably won't have a science textbook in my car trunk like Ash did in Army of Darkness, so I'll need to rely on my most unreliable memory. Or, I can use the chart at right.
Thanks Ilan for the tip. The original link and a much larger pic is here.
