You're right, there are also a lot of people who are capable of simply going to sleep. But if you think that there isn't a sizeable group of people in society who have difficulty with this, then I have news for you.
You're wrong.
Also when I state I have issues with this for 25+ years, do you really think I haven't heard these type of comments or advice? Because if you think your comment is something that I have never heard before, or am not aware of, then I have news for you again.
You're wrong.
The reason I'm replying: you're either trolling (if so, touche) or you're serious. Since you have 500+ karma (aka leave some good comments), I simply wanted to give you this feedback. Because I know my stuff when it comes to sleep by (1) dealing with, by (2) studying the neurobiology of it in my psychology undergrad multiple times. Moreover, I know the group of people I fall in (the group that has trouble with sleep). I can't speak for them but I have an idea of how they feel and think since I'm recognizing what they say in my own experiences.
