I've been noticing this of myself lately. I'm not a lightning fast typist, but I probably bounce along at around 60 words per minute, on average, and I am touch typing, i.e., I don't look at my fingers. Recently, I've found that I'll make a post, and then when I proof read it, or sometimes after I've posted, I'll find that I've repeat certain words, or sometimes whole sections of sentences. Apparently I do this subconsciously, and it's weird to come back later and see that I've done it. For example, it it could be as simple as something like repeating a pronoun. Other times I might actually repeat an entire actually repeat an entire piece of a sentence. I don't recall doing this when I was younger. I'm wondering if this could possibly be a sign of something else... Hopefully nothing serious... Anyway, thanks in advance for any insight you might be able to provide.
