Orlando - No I don't agree because the formula will fail as the age gets younger. For example we apply that formula to a 16 year old boy, he may very well end up with statutory rape. Otherwise the formula should have been just fine in order to stop these shameless cradle-snatching nonsense!
16/2 = 8
8 + 7 = 15
15 is underage if this dating is to incorporate sex, lol.
