Nor are people in their 20s (that is, both groups are having much less sex). That is the most worrying thing to me. People are not even engaging in the most fundamental, unavoidable, pleasurable human drive.
They seem very much like traumatized people, on a massive scale, just trying to survive.
Many people just get hungry and inhale the most convenient thing they can to scratch the hunger itch. McDonald's is always busy. People would be there on Christmas day if it was open. These people aren't into food as pleasure, they just don't want to be hungry. Of course with meal replacements bottles etc McDonald's isn't even the bottom of that particular barrel.
It's the same with sex. I've met people who define themselves by their sexuality. They consider it a primary pursuit in life. But for others it's just scratching an itch. I've realised I'm basically that way. It doesn't mean that much to me, it's just something my body makes me do. Porn is now everywhere and more easily accessible than drugs. People are now able to reach for McDonald's or the meal replacement, but for sex.
