A shallow angle from the sun give you that long shadow, but it also gives the light lots of extra air to pass through sideways on it's way down out of space. The extra air filters out more light, and without an intense enough light your skin won't make Vitamin D.

I feel famous now.

Black-body radiation is an interesting argument against 100% efficiency, but couldn't you just extrapolate and argue that the emission will be converted back to heat once it stops reflecting and becomes absorbed?

I might use the idea of horseback riding as an analogy. The neurotypical reflection of a human mind is a well-trained horse with a proficient rider. The rider is the concious viewpoint of the mind tied up with concious will. The horse is the rest of the mind (including the parts that control the body).

Someone with ADHD is riding a poorly-trained horse. It doesn't mean that the horse doesn't sometimes respond correctly to the commands of the rider, but it is far more likely to listen when the commands align with whatever the horse would prefer to be doing, and sometimes the horse won't listen at all even if the rider is trying desperately to get it to stop eating grass and get back on the path.

The analogy here drives home the idea that there is a disconnect between what the concious mind "wants" to do and what the rest of the mind is doing.

The analogy doesn't stretch very far, but by highlighting one of the major flaws of the analogy you can likewise highlight the painful irony of ADHD: to an outside observer there is no way to see that the rider is trying anything at all. This whole analogy is taking place inside one person's skull, and the entire concept of struggling to steer your own mind doesn't make much sense when you have a horse and rider that work so smoothly together that they feel unified.

What is a "gender ideologue"?
