Does Exercising Make You Drink More Alcohol?

Submitted by gary on

Comments: Good article, but they mix and match unrelated scenarios. The sxercising rats, that stopped exercising, drank more alcohol.

Submitted by gary on

I just completed a 6-part, narrated, power point presentation on porn addiction. It covers a lot of ground and explains so much of what we discuss on this site and have written about.
Subjects include - Coolidge effect, dopamine dysregulation, numbed pleasure response, rewiring of the brain, neuroplasticity, reward circuitry, limbic system, what makes Internet porn unique, what is an addiction, rebooting, learning & unlearning, and elk penises.

More evidence in humans of changes seen in animals - numbed pleasure response from overstimulation. A decline in reward activity associated with dopamine dysregulation. This is what is probably occuring with porn addiction - but no one studies it.

Stress: there's not a system in your body it doesn't poison in the end. Over time, it raises your blood pressure, increases your chances of infertility and makes you age faster, and that's not all. Remove the source of the stress and all those horrors vanish, right?
