All that jazz

I have a working familiarity with jazz, perhaps somewhat moreso than my average contemporaries. When I reach for a song to sing while showering or doing housework, chances are good I'll come up with a jazz standard.

Most jazz dates back to decades before my birth. I just realized that this means when I'm old, I'll be walking around singing songs that are like 100 years old. In the year 2040 I will be 60, so I will most likely still be walking around singing, and a jazz standard that was written in 1940 will be a hundred years old then! I am going to be such an archaic little old lady!
