More than 30 years ago, I urged BYU students
to avoid the promotional literature
of illicit sexual relations in what they read and view.
I gave this analogy.
Quote, "pornographic or erotic stories and pictures
are worse than filthy or polluted food.
The body has defenses to rid itself of unwholesome food.
With a few fatal exceptions, bad food will only make you sick
but do no permanent harm.
In contrast, a person who feasts upon filthy stories
or pornographic or erotic pictures and literature
records them in this marvelous retrieval
system we call a brain.
The brain won't vomit back filth.
Once recorded, it will always remain
subject to recall, flashing its perverted images
across your mind and drawing you away
from the wholesome things in life."
End of quote.
