This review from 2019 states:

> However, the effectiveness of sweat glands as an excretory organ for homeostatic purposes is currently unclear as there are no comprehensive reviews on this topic.

https://www.tandfonline.com/doi/full/10.1080/23328940.2019.1...

It also mentions stuff similar to the things you wrote:

> The role of sweating to eliminate waste products and toxicants seems to be minor compared with other avenues of excretion via the kidneys and gastrointestinal tract; as eccrine glands do not adapt to increase excretion rates either via concentrating sweat or increasing overall sweating rate. Studies suggesting a larger role of sweat glands in clearing waste products or toxicants from the body may be an artifact of methodological issues rather than evidence for selective transport.

However, the problem here is that normal sweating is taken into account, but discussion here is about sauna/exercise in which case sweating waste products approach kidney flux rates (which is why people do those things to detoxify) - human can easily sweat 1.5L per hour in that case, which is comparable to daily pee volume, and there are measurements regarding sweat composition that show comparable waste excretion:

    | Substance | Sweat (1h) | Urine (24h) |
    | --------- | ---------- | ----------- |
    | Urea      | ~0.3–1.2 g | ~20–30 g    |
    | Lead      | ~5–50 µg   | ~10–50 µg   |
    | Arsenic   | ~10–60 µg  | ~20–200 µg  |

Otherwise, I agree with you regarding focus - liver should be treated as sanctuary.

This is simply laughable and very easily checked out. Here is one random study:

> Many toxic elements appeared to be preferentially excreted through sweat

Here is another quick one

https://onlinelibrary.wiley.com/doi/full/10.1155/2012/184745

> Sweating deserves consideration for toxic element detoxification.

Its even observable directly - just go next to the heavy smoker during exercise.

While it might be less than dedicated organs, the skin is the largest organ by far.

Ofc, the topic is debated like every single thing in medicine, but calling it a myth is nonsence.

Some cells are still technically alive after 1 hour mark in the sense that there is no necrosis and cell membrane is still operating. This depends on cell type and nourishment - for example cells that have high amount of CoQ10 can live longer etc.

In any case, brain is definitely NOT 100% dead in a sense that ALL of its cells are necrotic which might explain why it is in a dream like state.

Also, I doubt 1 hour mark is regular thing in NDE.

No, "we" knew how to do it with 10x more money and people on the board, in a very unsafely manner. It was a few times muscle flex and thats why it stopped.

Making entire thing routine, cheap and safe is something else, and "we" don't know yet how to do that, or we would have at least few scientists constantly on the Moon.

It's a difference between running a marathon and dropping dead, and doing it all the time.

> we have ...[other]... problems

This kind of thinking is nonsensical. With so many people around, there can be arbitrary group of people working on any kind of problem, without them needing to point to other groups as doing imaginary problems. You talk like unless everybody works on solving specific problem, its not going to get solved. Life simply doesn't work that way, mythical man month explained it well why for one, and then, you can't know what unexplored spaces bring (maybe game changing discoveries).
