Why You’ll Never Be Able to Stop Thinking About Sex – If You Try

Spot a couple hotties at (your disgusting) gym spinning class, then go home to your partner and find it impossible to forget the way that Lycra shaped so perfectly shaped their asses? Science knows why!

Science Daily clues us in to a new study about why it’s so difficult to stop thinking something.

Mathematicians at Case Western Reserve University … found that just as thinking burns energy, stopping a thought burns energy — like stopping a truck on a downhill slope. “Maybe this explains why it is so tiring to relax and think about nothing,” said Daniela Calvetti, professor of mathematics, and one of the authors of a new brain study. Their work is published in an advanced online publication of Journal of Cerebral Blood Flow & Metabolism.

[…] To stop a thought, the brain uses inhibitory neurons to prevent excitatory neurons from passing information from one to another. “The inhibitory neurons are like a priest saying, ‘Don’t do it,'” Calvetti said. The “priest neurons” block information by releasing gamma aminobutyric acid, commonly called GABA, which counteracts the effect of the neurotransmitter glutamate by excitatory neurons.

And it’s like: Of course there’s a freakin’ priest metaphor in the very article I’ve turned into a post about sex.
