Modified Formula

Here is the original formula proposed by Prof. Tikku AKA Slim Shady

Love at first sight (a.k.a) Lust at first sight
= [(Length of the Stick * Radius of the tip) + No of minutes of the effective state under observation]/No. of sightings of your "pure love".

I think we have to add the following factor:

Sightu = A,
No. of sightings of "pure love" represented as B.

(See image below)..

so if B tends to infinity, the boy looses interest and looks for other A's

May be one of you should do an iterative experiment based on the following formula
