I used to have insomnia that came from anxiety about my future (I’m guessing.) When I started doing carpentry and started truly exhausting my body I gained the ability to sleep ANYWHERE ANY TIME FOR HOWEVER LONG I WANTED.
It’s seriously amazing. I’m 33 now and don’t have to work quite as hard, plus am used to the long shifts that are hard on your body. I can still sleep pretty much whenever, wherever.
I flew to England once (it was like a 14 hour flight) and seriously slept the entire time. I didn’t even have a window seat.
I mean, generally I don’t let that stop me from doing what I want to do.
But I drink a lot, so that’s probably why I don’t care as much.
