A very big change in America regarding marital infidelity. The rate of cheating husbands has dropped significantly over the past thirty years, by half, while the rate of cheating wives has remained at the same level. And American sociologists say that for the first time in history, the proportion of unfaithful wives has become greater than the proportion of unfaithful husbands. (I'm sure the same trend now exists in Europe and Russia).
