The fiancee formula

Just when you thought all those algebra classes were useless, the Daily Mail serves up this handy mathematical way of finding out when you should put a ring on it.

Dubbed the Fiancee Formula, the equation offers your optimal proposal age. Here's how to calculate it:

*Choose the OLDEST age at which you would want to get married. Call this number "N."

*Decide the EARLIEST age at which you would want to get married. Call this number "P."

*Subtract "P" from "N" and multiply the result by 0.368

*Add that number to "P."

Bam! You've found your optimal proposal age.

BTW: My answer was 28, which coincidentally is my current age. Looks like it's time to get cracking.
