You don't have to do this part if you don't want, but the results should be REALLY fun

(see http://en.wikipedia.org/wiki/Digit_ratio for a good explanation of why)

In exchange for doing this annoying thing, you will be entered into a drawing to win a monetary prize, as below.

Please measure your digit ratio according to the following instructions adopted from the University of Cambridge:

1. Place your right hand firmly on the plate of a photocopier or scanner with fingers straight. Close cover of place a sheet of paper over your hand to prevent glare from overhead lights. Ensure that the bottom crease and finger tip can be clearly seen in the photocopy.

2. Use a ruler or calipers to measure the distance from the middle of the bottom crease to the tip of the finger to the nearest hundredth of a centimeter.

3. Once you have the measures for both your ring and index finger, then divide the length of your index finger by the length of your ring finger. The result is 2D:4D (2nd digit divided by 4th digit).

If possible, please give three digits - for example, 0.915. Some people may have digit ratios slightly greater than 1, which is okay.
