Similar here. I have a good job, but am not independently wealthy or any of that horse pucky (though saving like mad to get there). I rarely set an alarm, and mostly wake up before it goes off when I do.
I prioritize going to bed at a reasonable time, and avoid alcohol and especially sugar for at least 2-3 hours before bedtime. We do a crossword before lights out to give a guaranteed 15-30 minutes of non-screen time before lights out and tend to sleep much better than when I did ipad time up to lights out.
I have a smart phone, but choose to avoid getting hooked on it. My work would let me get email on it but they then have the right to wipe it at will if I get terminated, which is a deal breaker for me. If I REALLY am expecting something important I have a work laptop I can fire up. Mainly I use to to double check our German colleagues have not canceled a 7AM meeting before I ride my bike in.
The 2nd level parent comment is a complainy pants and needs to start taking control of his effing life. Get a better job, go to bed earlier, or similar adjustments.
At the risk of breaking the smarmy-fest, I find that my life experience is completely different.
I have young children and a busy workload. I do not have time to ride a bike into work, to avoid eating 2-3 hours before bed, or to sleep more than 6 hours a night. Really, it's more like 4-5.
So I use my phone as an alarm clock. Then, immediately after it wakes me up, I use it to deal with any timely emails while I am sitting on the toilet and waiting for the shower to warm up. I do this because I am aware that my colleagues may need that information to proceed before I arrive at work and it is the only time I will get to spend on email until I have gotten the kids up, kids fed, kitchen cleaned, kids to school, and myself to work. My spouse works too, so there is no homemaker to do these wonderful responsibilities for me.
I expect that most people in my life situation follow the same routine.
Now, while you are contemplating your indignant reply to restate how I should "taking control of my effing life," please keep in mind that some people actually like to work harder than you, for longer than you. And that others may not have the opportunities that you had to "get a better job, go to bed earlier, or (make) similar adjustments." Maybe you can use some of that bountiful time you have in your monk-like day to think about how arrogant and elitist your post comes across as, and how to restate your opinion more considerately in the future so the other 99% of us don't blow you off.
