age disparity have developed over time and vary among societies.

Differences in age preferences for mates can stem from evolutionary mating strategies and age preferences in sexual partners may vary cross culturally.

Bloggers and busybodies are divided over whether or not the age difference between actress Jennifer Lawrence, 24, and musician Chris Martin, 37, automatically renders their relationship inappropriate.

“relationship expert” Tracey Cox condones it, saying their common ground should count for more than their 13-year age gap; other commenters, meanwhile, condemn Martin as “creepy” and Lawrence as “lame.”If you subscribe to the “rule of seven,” the question of where the boundaries of a socially acceptable relationship lie aren’t a matter of opinion—they’re clearly defined.

Thus, both sexes will have to compete and be selective in mate choices.

These two theories explain why natural and sexual selection acts slightly differently on the two sexes so that they display different preferences.

The rule is widely cited, but its origins are hard to pin down.

In its earlier incarnations, it seemed to be a prescription for an ideal age difference rather than the limit of what’s okay. An 18-year-old's range is 16-22, whereas a 30-year-old's might be more like 22-46. The second graph is labeled Dating Pool, and is a bell curve.
