Experience number 10^20
The existence number is 10^20. We cannot count the number more bigger than this by my 10 fingers. We can guess it, but it is out of my experience. As a result, there are a lot ways to count the existence number. For the example, 100 is the perfect number. 4 fingers have 12 joints and the thumb has 2 joints, and each hands times together that (122)*(122)=100. It is the experience number.
