I have serious insomnia, as in a "medical condition" that affects my mental health.
This didn't happen overnight and I am old, so I just wanted to encourage folks to prioritize sleep hygiene. You don't want to wind up like me.
Travelling helps a lot, in some ways more than 215. It seems counter-intuitive, but because I am more mindful of my surroundings and less likely to use up precious electricity and data on lighting and ruminating on the internet, I sleep better.
You need more sleep as you get older. I can keep up with folks in their 20s or 30s for a day, but the next day I'm like a turtle in its shell resting up for the next time.
That said, there are biological and scientific reasons why people in their teens and twenties cannot and should not be expected to adjust their sleep schedules to accommodate 8 AM classes and morning shifts for the convenience of us oldsters.
Great topic,
@Wabbajack; I like you and I hope you stick around for awhile.
