Hi folks this is just amazing. I have been doing this as long as I can remember, It's become a bit of a novelty to my friends. I can count the number of letters in a sentence up to about 40 characters in under a second, assuming I can spell the words. I also add the numbers on car plates as they pass me. I cannot alphabetize however, and I am not obsessively tidy or compulsive when it comes to daily life. I also have to count numbers to a conclusive multiple of 4 or 3 or whichever my brain chooses in the moment. for example if I see the numbers 346 on a car reg plate, I have to quickly visualise to a multiple of 4, so I see 1231 2341 2345 6123 1234 1234 5612 3123 4123 4561 2312 3412 3456. The sequence must be completed and must end on the last number of the last digit, but the entire process only takes a few seconds. Does this make sense to any of you out there? I love that others share a similar ability, though I actually enjoy it and don't see it as a burden at all. Also I barely scraped a pass at mathematics in school, posess a vast general knowledge of things I did not intend to learn at all, and have never been able to focus concentration on any given subject for any prolonged period of time. Never did any homework when young, never studied for exams, but passed everything. Teachers at school considered me to be a 'coaster' but I genuinely feel that my brain just goes to sleep when I have to listen to someone instructing me, I just cannot learn that way. Any and all comments or replies are very much appreciated. Please stay safe everyone and kind regards from Bonnie Scotland!
