A rising percentage of #US #teens aren’t getting enough #sleep
A national survey found 77% of #highschool #students didn’t get adequate shut-eye in 2023
A study of five Minnesota high schools followed students over about two years as two schools delayed their first bell by an hour or so and three kept theirs at 7:30 a.m. The students with a later start got more sleep and had fewer symptoms of #depression than their peers with an early start.

Teens need eight to 10 hours of sleep each night. A large majority get less than that, according to a national survey of U.S. high school students.

Want a delay in a bash script. And you don't like to see the sleep command polluting your ps output? Try this:

#!/bin/bash
pipe=$(mktemp -u)
mkfifo "$pipe"
exec 3<>"$pipe"
doSleep() {
read -t "$1" -u 3
}

It opens a UNIX fifo file on file descriptor 3, deletes it immediately so it does not show up in the temporary directory and cannot be fooled around with. The doSleep makes use of the timeout feature of the builtin read command. Have fun sleeping.

Yeah, brushing teeth... brushing teeth, #brushing #teeth, brushing teeth...
It's #addictive! You know that? 🤔

In the #morning, right after getting up... and then, because it's not enough, again in the evening, right before bed, because otherwise you can't drift off to #sleep peacefully! 😜

I even take the stuff with me on vacation when I travel... ✈️
I can't get enough of it! 😉

SO: BE WARNED! ⚠️

Just when we think that the world can’t get crazier, we get a reminder that life can surprise us. April is a curious month, filled at times with rain, snow, or sunshine. The current full moon in Libra asks us to consider balance. February’s Saturn conjunction with Neptune at zero degrees Aries was the wave of the green flag, letting us know that we could and should accelerate to full speed as we begin this part of our journey.
