More Than One Way to Count

Something as simple as counting is not as simple as it seems.  As I can observe, many people only learn the standard counting, 1, 2, 3, 4...


I am not sure if it has to do with the Hong Kong numeric education, as it appears I also do 2, 4, 6, 8... and 5, 10, 15, 20...  As it turns out, using the same method to count get tiring very easily!  I am glad I have the skill to change method to keep it fresh.
