But OP did really meant that people who can't use PCs are braindead idoits, which is very harsh. People who are using PCs at their workplace for the first time or have learnt using Windows for the sake of getting a job do be very cautious like that. They only used them in constricted way and never got to play around with it. You can never learn how a device works without playing around with it imo. Just because you had more experience with PCs doesn't mean you have right to call who are inexperienced brain-dead idoits.
I have tried this REM cycle theory for me. It doesn't seem to matter for me. I have tried waking up at 7h30m for few days, I felt very groggy to wake up especially in this cold weather. But somehow waking up at 6hrs, almost as if I haven't slept at all. My takeaway was that the longer I slept, the stronger sleep I had and the harder it was to wake up whether or not it was at end of the cycle or middle.
I like time with my family. I just don't want it to be extravagant.
Being on keyboard doesn't me I shut myself from all social interactions.
