Hi Dev,
Been replaying TTS, following the science club route.
Couple of things.
When being taught basic Volleyball moves by Reiko, she comments on Naoto's "complexion" and movements. Complexion is mostly about skin colour and condition. Physique might be a better match to the intent.
I won't argue it here, but I point out you could buy yourself a ripper of an argument in physics circles by asserting that life defies entropy. That's a pretty controversial point of view, and there's a ton of counter-argument to that stance. A lot depends on the timing and where you draw your boundaries and if you get them just right, life appears to reduce entropy for a while. But the case that entropy, over all and over long times, just grows without limit is pretty convincing, life or no life.
Gloves and acids are definitely a safety thing. The wrong glove gives a false sense of security in protecting hands from a spill. For some acids, some gloves provide no effective protection, being eaten through quickly or even bursting into flame. In the case of an acid spill, you could easily do more damage to the victim getting the glove off than if you just flood the injured area with water. Many labs have safety showers for just such a purpose in case delicate parts like eyes are impacted.
YouTube's NileRed, who knows a thing or two about chemistry, looked at some common gloves vs conc HNO3. You can see it here: NileRed:conc HNO3 vs gloves There's another NileRed video (re-uploaded by someone else) where NileRed pours acids of various types on his bare hands (Do not try this yourself anyone who reads this). See it here: Acid vs hands Scary but pretty convincing.
Information on which glove to use for reasonable protection can be readily found in several places, this is one for example: Safety Glove compatibility
