Netterment 

The act of wanting to better yourself after 40, but having negative consequences instead

I was trying to exercise but to my netterment, I threw my back out instead.

The theory of Bettermentflux posits that even if it's not clear how, things ultimately have a way of coming together and getting better.

Synonym of entropy, the theory that the natural order of things is a slow devolution into chaos and disorder.

The recipe tasted like ass. So I threw it in Tupperware and ordered some pizza. It must have bettermentfluxed overnight, because damn is it tasty now.
