Thinking too deeply

If you think of a animal like a dog, and you think of it like: "This dog was a wolf, but if it was a wolf... what was it before?" And you spend 73 fucking hours on the same subject to realize that you've been wasting time on hurting your brain when you had go to school.

"Hey, i ate meat, but this meat was a animal covered in oil and butter and it became food like this... what happened to that in the meantime of becoming meat?" *starts thinking too deeply about the subject*
