Sponge factor

My sponge factor seems to be at an all time high.

What, dear narrator, is a sponge factor?

Well it is obviously a phrase I just made up. It has nothing to do with Max Factor sponges or the availability of your favorite loofa in your favorite store.

I shall define sponge factor thusly:
The propensity to absorb knowlege at varying rates. A high sponge factor would indicate an insatiable desire for knowlege and a low sponge factor would indicate a bump on a log.
