This was my logic. The type of girl I'm into, I'll not meet because of this logical fallacy. I was beyond lucky, the probability were so low, yet I found her.
Being single and horny tends to get people off the couch from time to time. Then you meet people you vibe with and you get to sit on the couch together because you're no longer lonely or climbing the walls with hormones.
You'd like to think so, but I've heard some stories about what folks at the senior living center get up to. It's only "uninterrupted couch time" in the JD Vance sense.
I think that might also be because of boredom. When there is nothing else to do people tend to do that.
For example, in a place I know they were struggling with not having enough electricity for the population. So each day there'd be no electricity for hours and hours. That resulted in a clear population boom after a few years. And went away after the power problem was solved.
