I lost the internal monologue during puberty. It was initially pretty scary when I noticed that -- it though I&#x27;m ceasing to exist, and in a few years the &quot;me&quot; will be gone from my shell, while everyone else around me will be none the wiser. Fortunately, it did not happen (yet).<p>I think the way it happened was that as I read lots of books, I realized I need to stop processing consciously every word if I want to read faster. Additionally, I started to spend lots of time interacting with English language (which is not my native), and I was sometimes thinking in English before I stopped thinking in words altogether.<p>I developed a speech impediment because of that: whenever I need to speak, I need to synchronize my mental state with the words coming from my mouth, which requires a little effort.
