I understand your confusion about using "entropy" outside a thermodynamics context, and you're absolutely correct to point out that the term "entropy" originated in the field of thermodynamics. However, the concept has been extended metaphorically in other fields to describe systems of complexity and order. It's in this latter, metaphorical sense that I'm using the term.

Now, let's apply this to living systems. Organisms are highly ordered, containing complex structures at various scales from cells to organs. They can maintain and even increase their internal order, or decrease their "entropy," by consuming energy from their environment (like food). This is the "detour into lower entropy" I was talking about.

While this seems to contradict the second law of thermodynamics, remember that organisms are not closed systems – they constantly exchange energy and matter with their environment. The increase in order within the organism is more than offset by the increase in disorder in the environment, resulting in an overall increase in entropy in the universe. This is completely consistent with the second law of thermodynamics.

What I find fascinating is that life can maintain this high degree of organization for such a long period of time, despite the natural tendency towards disorder. This is not to say that the process is unexplained; science has a lot to say about how this happens, but rather that it's a remarkable (and seemingly unique) characteristic of life. Does this make more sense? I hope this clarifies the concept a bit.
