Ha, I'm also relieved to have found this forum and realize that there are other people like me who can quickly count the number of letters in words (though I don't do the alphabetizing nor the splitting into 3's). It's actually not that big of a problem for me and is not something I do all the time, more when I want to or to amuse friends (it's a great party trick).
Does anyone have any insight on (1) where this comes from and (2) any practical applications for it? The urge to do this compulsively obviously has something to do with being OCD, but the ability itself to quickly count letters in words is something which I've found other people cannot do no matter how hard they try, so something else must be at work. I'm quite good at learning foreign languages and have always wondered whether there's a connection there (seems doubtful, but who knows)...anyone else?
