It's strange how many people say 'worrying' in this context, number theory isn't a source of anxiety it's fun!

People like the Mayans used a base 20.https://en.wikipedia.org/wiki/Maya_numerals

Some it sounds a bit like good old Pareidolia:"...the tendency for incorrect perception of a stimulus as an object, pattern or meaning known to the observer, such as seeing shapes in clouds, seeing faces in inanimate objects or abstract patterns, or hearing hidden messages in music."

Yes, my maths teacher at school said that the number of petals of most flowers is a member of the Fibonacci sequence.

The petals thing is another Fibonacci myth, based on a very selective reporting, see this quote:Wilson cites numbers of petals on flowers.lily 3 violet 5delphinium 8mayweed 13aster 21pyrethrum 34helenium 55michelmas daisy 89These examples associate with Fibonacci numbers. But Wilson neglects to mention these others:many trees 0 This is a Fibonacci number. [3]mustard, dames' rocket 4 Not a Fibonacci number.tulip, hyacinth 6 Not a Fibonacci number.starflower, eggplant 7 Not a Fibonacci number.gardenia 8, 9 or 10 petals. 9 and 10 are not Fibonacci numbers.Greek anemonie (various) 14 or 15 Not Fibonacci numbers. black-eyed susan (some) 14 Not a Fibonacci number.mountain laurel 10 Not a Fibonacci number.gazania 16 Not a Fibonacci number.https://www.lockhaven.edu/~dsimanek/pseudo/fibonacc.htm

But even so, how meaningful is it to take a single number, or even two numbers, and say "this is a part of THIS sequence"?But I suspect it all originates with a desire to find a divine order to things (or even any order).

Interesting but probably irrelevant:In every chocolate company I've worked with, I've found at least one guy with a finger missing.

If you count on your fingers you get to a full set of fingers which is 10. You then start with a new set of fingers and remember 'I've already counted 1 ten'. That is base 10.
