The average marriage in a 'merica is 7.62 years .... oddly the same notation that the Soviets have long used for their caliber of choice for the AK-47.
You might actually face a better chance on the battle field vs those rounds than in the realm of marriage. I was in the military for 15-20 years (depending upon which agency counts) EVERY team mate that I served with that was married ... was no longer married by the time they returned from deployment.
Play as you will - consider yourself well warned.
