entropy (or decay) represents the amount of energy input to the system which does not participate in work done by the system.

It’s easy to be selfish.

[Left alone, all things move towards entropy]

It’s harder to be selfless.

[The system needs constant energy input.]

Can you dig it?

[Hint: complexity of action(s) (but not necessarily the number of moving parts) applied to the system does not equal less entropy]

Can you narrow it down and dial it in?
