I'm 53 and have always suffered from boredom. Lets just say school was frustrating.
I didn't have internet till I was 26 so it cannot be blamed for shaping my brain as I grew up like kids today who were born really after 1990. I think the internet is shaping our brains to ALWAYS have STIMULATION. Its addictive really.
When I was a kid I slept with a fan on for the white noise it provided, it relaxed me. I now fall asleep with a fan and wireless headphones on playing some podcast. If I don't, I will be lost in my own thoughts and cant sleep. I need something outside myself to focus on.
This was a first for me. A couple of falls back the wife and dog and I took the 20 ft travel trailer up to the blues to camp for a couple of nights. There was NO wind, and NO moonlight. That night as the wife and I tried to sleep in the NARROW bed I believe I came the closest to having a panic attack I ever had. It was completely SILENT and completely DARK. I felt confined in the narrow bed, like I was in a coffin buried underground, my brain could not turn off. I got up multiple times to sit and read, hoping I could relax. I never did fall asleep.
