when i was younger, maybe 7, i used to multiply by two a lot. i'd do it in my head and i would do it often. i dont know why i started or why i stopped or why i didnt go to higher numbers. i dont remember being trained to multiply at the time so i dont even know how i used to do it.

i'd multiply 1x2 = 2

2x2 = 4

4x2 = 16 8

and so on

the farthest I remember reaching was 1024, though I may have reached 2048 once. i dont know why i didnt go higher than that.

another thing i used to do was tap my fingers in a pattern, LRRL, so left tap, right tap, right tap, left tap. then i'd expand that pattern, LRRL, RLLR, RLLR, LRRL, so it would be a bigger pattern of the same pattern. like multiplying i'd just do this to see how big i could make the pattern. i'd do this by tapping my index and thumb finger. to an observer it would probably appear as if i were 'stimming'.

did anyone else do things like this?
