Studies show that depression is more prevalent in people with higher I.Q's.
Reason.
As you grow older the more intelligent you become and the harder it is to entertain you. For example.  When watching a movie a more intelligent person is likely to point out the plot holes or the "that's not possible" why would the writer and directors put that there?.
This is a serious problem. Not having the ability to be entertained leaves an intelligent person with nothing but facing and thinking about the cold hard facts of this world. And that is very, very depressing.
The reason it's so fun to be a child is because you are yet to understand the horrors this world has. Tag entertains you. You are happy with the simple things. But.
When you go back and try to do any of the things you did as a child you always catch yourself saying "man.. I don't know how I thought that was cool". Even playing video games aren't the same.
So..
Conclusion.
If you are depressed.  It may only be because you are a very intelligent person and this world has alot of darkness.
You are not alone. 🙏

Once you realize and understand this.
You will really start to ponder on what this place is?
If intelligence is torcher...
