There are people that suffer from this self afflicted syndrome and it's not easy to change your lifestyle into a healthy one. Hiding behind words like night owl doesn't help you if you want to change yourself however.
And if you don't want to change yourself, then just admit to yourself that this is the lifestyle you want to have.
There is nothing inherently wrong with wanting to stay up late/sleep in. It is however a decision you make and not a biological necessity.
Not sure why you are attacking me, and I never said I was a night owl or that I wanted to change myself.
Anyway, if you consider genetic predispositions or adolescence to be “self afflicted syndromes”, then either there’s a language barrier or you just will never accept something that it’s not your own opinion, even if there’s scientific research showing you otherwise (maybe you didn’t read it? If so, then I suggest you do).
Obesity exists as well and is usually caused by the lifestyle of the afflicted. The same applies here.
I'm sorry for my phrasing however, there is a language barrier as you've correctly pointed out and I was using the "you" as a generic term for people identify with that.
It is scientifically recognized that people have different circadian rhythms (thus sleep cycles).
And here’s some research about teenage delayed circadian rhythm: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2820578/
You know, sometimes people are not snowflakes that require bullying or discipline to do things “the right way”.
Btw, do you have any references for your claim that most sedentary people will become night owls if they don’t pay attention? Or is it just your own personal perspective?
