2nd Wife Rule

A mathematical equation to determine the age of a man's second wife: you take the man's physical age divided by two plus 7 years and that will be his second wife's age. The rule is also true to women who are first-time widows or divorcees but in reverse: Take her age, subtract seven years and multiply by two and that's the age, plus or minus a few years, of her second husband. If she's 44, she should start hanging out at nursing homes and VFW lodges because her next husband will be in his 70s. (You have to allow greater margin of error the older a woman's second husband's likely to be.) The problem is there are more women who are divorced in their 40s and 50s than there are single men in their 60s and 70s. Hence, further validation of the line in "Sleepless in Seattle" that "it's easier for a woman to be killed by a terrorist than it is to find a husband over the age of 40."
