Quitting adult entertainment makes a HUGE difference. That shit really rewire the brain in an evil way. Today we are so desensitized because we have ANYTHING for free on the net. I remember as a kid I would get literally Priapism just by watching a VHS tape all fucked up low quality. Because it was impossible to get my hands on adult entertainment. Internet did exist, cell phones didn't exist, computers where nor accessible yet, etc. Today watching adult entertainment is pretty much like watching a tv show while eating, and every kid has access to.
On a side note about Alzheimer, remember is one of the fastest growing diseases in the US right now. Make sure you consume PLENTY of cholesterol and animal fat in your diet. Up to 75% of the brain is made of fat and cholesterol, all sex hormones are made from cholesterol. All the nervous system is made of cholesterol. NEVER take cholesterol medications, is one of the most dangerous drugs ever created and many studies point to them as one of the main contributors of risk of Alzheimer.
