So as for pornography viewing, what exactly do they think would have changed in a person in 24 months?
Why not 12 or 36 or 2?
Silly! It's a biblical number with incredible significance! You see ... 2 and 4 represent the 2nd and 4th book of the bible, specifically Exodus (6 letters) and Numbers (7 letters). 6 x 7 = 42. If you take the inverse of that (representing the flip flop of doctrines), you get 24. See? It makes perfect sense.
