I think home improvement stores should be required to keep stats on the marriages of their customers.
I should be able to know, before I enter a store to say look at granite for four hours with my spouse, that the customers who shop at that store have an "x" percent success rate in their marriage.
Stores could use this as part of their marketing. "More happily married couples chose their appliances at this store."
Also, all those shows on HGTV? They should be required by law at the end of the program to tell you if the couple is still married.
Just a thought.
