This study only covers one source of lead poisoning they would have faced.

The "black one" is an SR71 Blackbird... and it is badass.

During gas mask training, it was used as a torture device... They let off so many in a small shed that we couldn't see more than a few inches.

Why is every RC aircraft now a "Drone" on this site.

The other day an article about the guy who was fined by the FAA... he was flying a cheap RC plane, not a "Drone"

Even if its a multi rotor doesn't make it a "Drone" either.

I thought the "wrinkled skin" thing was beyond your studies focus.

You notice that they say the skin mediates...

Its more likely that this was more about studying the material and its properties than it was about skin. The reference to skin may have been an assumption.

Well... the feeling that it is more fragile is not really so. The wrinkles may be more likely to catch a sharp edge, but the structure itself is still strong. I can grab just as hard when wrinkled or not... I have not had a problem with pain.

Well, seeing as there have been studies that show that you can soak only one hand in water and the other dry hand will also wrinkle...

As I said to Ice...

I believe the study mentioned is making the assumption of skin absorbing water and getting wrinkled.

The response may not be instant, but it is fairly quick, just a few minutes usually.

How has is been debunked? Studies? Where?

Also the fact that only the hands and feet exhibit the level or wrinkling that they do. The rest of the body does not.

Well... the skin does absorb water. It may not be the cause of pruney skin, but it does absorb water. The reaction and behavior of keratin when absorbing water and how it is released is important. This can enhance our material science knowledge, even if it does not explain pruney hands.

I am more inclined to believe the newer studies. The earlier given reasons were more educated guesses than actually studied. (good guesses, based on the knowledge of the time, but I don't think they were directly studied and based on the results)

Because its driven by the nervous system...

Many new shooters find this to be true... Smaller calibers are easier to shoot well due to the lower recoil causing them to not stress as much when firing.

The problem is perspective... and opinion.

Ah yes... also if I came off as an ass in my prior, I am sorry. I re-read it, it was late and that is not my normal standard of discussion...
