You can count past 1,000 on your fingers by using binary, instead of just 10

I have the gene where my second thumb joint/knuckle near the base doesn't bend. I can only count to 10 using this method. 11 and 12 are not really reachable. Even 9 is a bit of a stretch.
Worst hypothesis, even if counting just to 8, you're still using a single hand, so it's an improvement over counting to 5 with fingers. Couple it with the other hand and you're counting up to 64.
There's also the Chisanbop method @hesh@quokk.au mentioned, for that your unbending joint shouldn't be an issue, and it allows you to count to 9 with a single hand (99 with both).
