Found an interesting newish hypothesis on the relationship between life and entropy.

Although entropy must increase over time in an isolated or “closed” system, an “open” system can keep its entropy low — that is, divide energy unevenly among its atoms — by greatly increasing the entropy of its surroundings. In his influential 1944 monograph “What Is Life?” the eminent quantum physicist Erwin Schrödinger argued that this is what living things must do. A plant, for example, absorbs extremely energetic sunlight, uses it to build sugars, and ejects infrared light, a much less concentrated form of energy. The overall entropy of the universe increases during photosynthesis as the sunlight dissipates, even as the plant prevents itself from decaying by maintaining an orderly internal structure.

Don't think I really understood it, but what I gather is that life keeps its own entropy low (maintains order) by increasing entropy outside itself. Maybe in some sense that's how all ordered systems maintain themselves?

Thanks Blondel having lived with autistic kids I know how strange they appear.

I have long suspected that lack of D3 especially it pregnant mothers was the major problem. This is certainly correlated with the rise of sun blocker usage and fear of the sun which means that autism is iatrogenic (doctor caused). UVB is very beneficial in fact it is required. I never once thought the parent's responsible. I remember my childhood and how I used to play in the sun with only a t-shirt and shorts and high top black tennis shoes. All the girls I knew in the late 50s wanted a tan! Nobody heard of autism. Then around the early 80s, entered the sun blockers and the sun scare. Autism has become a racket like cancer (they know the cause of it too which is microbial which means it can be treated with antibiotics. A recent study confirms this ).
We truly live in the dark ages.

I’m not convinced of the second law of thermodynamics, that entropy always increases. It may be so in certain classes of situations, but I’ve never seen a global, all-encompassing proof of it, and until there is a proof, in my eyes it remains a theorem.

Technically, no theory can be proved. But as Stephen Hawking puts it, "if a theory is mathematically consistent and always gives predictions that agree with observations, we can be reasonably confident it's the right one." And this is the case of the second law of thermodynamics and entropy. So I guess you may never be satisfied, but there's reasonable confidence this is how our universe works and nothing has yet to contradict it.

From the standpoint of physics and the uncertainty principle, life creates more disorder (entropy) than it does order. For example, the energy via heat given off of the human body (adding entropy) is greater than the order created by memorizing these words. Assuming our universe is effectively a closed system and the laws of physics are uniform, which seems to be the case observationally speaking, the arrow of time we experience going towards the "future" corresponds to the arrow of entrophy increasing (as it cannot increase) per the second law of thermodynamics. Something to think about.
