When I was a postdoctoral fellow at the Roche Institute of Molecular Biology in the early 1990s, I was fortunate to work with Sid Udenfriend, a pioneer in the biochemistry of the brain and a real mensch. Sid's favorite pedagogical phrase, usually intoned at the bar, was "It's always good to know a little chemistry." I couldn't agree more. It would be possible to write a book exploring the brain's pleasure circuits that was free of not only molecules but also basic anatomy, but that sort of spoon-feeding would require ignoring some of the most interesting and important issues, and so that's not what you'll find here. If you come along for the ride and work with me just a bit to learn some basic neuroscience, I'll do my best to make it lively and fun as we explore the cellular and molecular basis of human pleasure, transcendent experience, and addiction.
Traditionally, there is also a lot of overlap on the Venn diagram between "sister-wives" and "child brides." The leader of my old church married two of his nieces when they were just 16, as well as a third 16-year-old girl from another family. Then there was my sister's brother-in-law, who was accused of molesting his daughter. He admitted to it and was excommunicated ... then welcomed back a week later. At least two other men were accused and convicted of molesting their children. One guy had four daughters, every one of them a victim -- he spent years in prison despite his wife's defense of him.
As we've noted, it's very easy to turn into an asshole and cause yourself a wealth of problems. Try to keep a cool head when arguing and you'll find yourself much more successful. The more polite and calm you remain the less likely that the argument will escalate into a shouting match, since you're just fueling the fire at that point. Instead of grasping at the anger in the moment, concentrate on the outcome. You want it to be good and everyone to end up happy in the end, so stay calm. It's hard to be mean to someone who's continually kind, so keeping a level head—even if you have to fake it—will make your arguments turn out a lot better.
