Most people laugh when I ask this question. Then they tie themselves into knots trying to answer it. Explanations are usually accompanied by diagrams featuring stick figures.
Actually you can answer it in less than 50 words, without diagrams.
Here’s the question.
When you look in a mirror, your left and right are interchanged. Why doesn’t the mirror also turn you upside down?
Remember — 50 word maximum for the answer. No prizes.
I’ll give my answer in a week (November 18).
