Recently, mathematicians are claiming to have found the formula that predicts how long love will last. Research commissioned by Microsoft has revealed a new love equation that determines the key ingredients to a successful, long-lasting relationship - with factors such as a good sense of humour ranking in importance alongside number of previous sexual partners.
L = 8 + 0.5Y - 0.2P + 0.9Hm + 0.3Mf + J - 0.3G - 0.5(Sm - Sf)2 + I + 1.5C
L: The predicted length in years of the relationship
Y: The number of years the two people knew each other before the relationship became serious
P: The number of previous partners of both people added together
Hm: The importance the male partner attaches to honesty in the relationship
Mf: The importance the female attaches to money in the relationship
J: The importance both attach to humour (added together)
G: The importance both attach to good looks (added together)
Sm and Sf : The importance male and female attach to sex
I: The importance attached to having good in-laws (added together)
C: The importance attached to children in the relationship (added together)
All measures can be scaled from 1 to 5 where 1 is not important at all and 5 is very important.

Candle-lit dinner + kissing = a call back.
Timing + communication * mutual attraction - emotional baggage = intimacy.
