Kaliyug

1 billion years in passing or 20, does it make a difference? But it
Does: at 14 billion, it was all poof in a nada sort of a way so …

5000 years in digressing or 10000, same difference: around 10,
We all ploughed, and at 5 we slouched while others ploughed.

The slouchers had time enough to think up Kaliyug, the dark times,
Commencing about the same time at which the slouching began.
