Entropy may kill you but it also keeps you alive since the irreversibility of your chemical reactions generates body heat.

The heat our body puts out is still technically capable of doing physical work

Ergo, not entropy

The entropy of one system becomes the starting state of another. Tending towards entropy doesn't mean that a transitional state is not entropy.

Entropy is simply the measure of energy in a system, particularly an isolated system, incapable of doing physical work. Your body converting food into body heat is an exothermic reaction, a reduction in entropy.

Entropy is a system declining in it's order. Saying a reduction in entropy is like a double negative.

No, saying a reduction in entropy is saying you've added energy to a system.

Turning on the oven reduces entropy inside the oven

Quoted By:

entropy is a measure of the disorder in a system.
every attempt to describe it in more detail will raise contradictions so let it be.

Energy was added to the electromagnetic system, entropy of that system was heat as a waste product in the heating coils. There was a system if cold air with the oven prior that received this heat into this system but the heat itself it a byproduct of another systems tendency towards entropy. You are confusing open systems. The oven is not a closed system unless you are using an idealistically perfect oven.

Brainlet comment.
You're not gonna do much work with low grade heat because (1) Carnot efficiency sucks with small T and (2) S = Q/T is entropy.

Entropy is literally a made up concept.
