Shoe Magic

This is a neat little trick where your shoe size can determine your age.

1. Start with your shoe size... if it's a 1/2 size round up.
2. Multiply that number by 5
3. Add 50.
4. Multiply by 20.
5. Add 1013.
6. Subtract the year you were born.

The first two (or one) digits are your shoe size, and the last two digits are your age.
