Additionally, in astrophysics the term "metal" includes many elements which are not metals in any other field. Astrophysically, metals are any element other than hydrogen or helium, so in addition to ordinary metals like sodium and lithium non-metallic elements such as carbon and oxygen are counted as metals.

Whilst the USA might be having an unusually cold snap, how often is the temp below 0F there, other than Alaska?

Quite a bit, actually. In my hometown in New York in January the average daily low is just above 0F and it was often colder than Anchorage or Fairbanks, Alaska. It wasn't unusual to have daily high temperatures below 0F. The record low was -37F. I'd say below 0F isn't at all unusual above about 40 degrees north latitude in the US except in coastal areas; you're probably talking about 1/3 of the continental US.

For one, Miller was an NFA case dealing with short barreled shotguns which upheld the NFA. But, contrary to gun control advocate's wishes, the ruling really didn't hinge at all on the collective vs. individual right debate; the only real discussion in it had to do with the type of firearm and whether that type was protected. Had the Court subscribed to the view it was a collective right related to actual militia service the Second Amendment examination would have ended with the determination that Miller was not a member of a the organized militia and wasn't carrying the shotgun pursuant to militia duty. Examining the firearm and not the person suggests they view it as an individual right.

The Heller opinion actually contains a pretty good discussion of what Miller is and is not and a number of peculiarities surrounding it.

Which, grammatically, isn't explanatory not operative. The operative part of the 2nd Amendment is, in full, "the right of the people to keep and bear arms shall not be infringed." In modern construction and words (based on Supreme Court decisions, specifically Heller and Miller) the full amendment would be something like, "Because a well-trained militia is necessary to the security of a free state, the right of individuals to keep and bear arms of military usefulness shall not be infringed." The first clause only explains why it's not be infringed; it doesn't impose a limit upon it.

Well, Miller did somewhat limit it based on the militia clause, by saying a firearm which wasn't demonstrated to be militarily useful was not protected, implying that if it had been demonstrated to be militarily useful it would be protected. So, under Miller, an assault rifle (obviously of military usefulness) would be protected but maybe not a break action shotgun. It's an odd case, at any rate, since Miller had died before it reached the Court and his side didn't argue before the Court.

I find it a bit ironic that the NRA doesn't even mention lead poisoning their own membership. Or maybe that explains a lot about the NRA.

Actually, the NRA Range Source Book does mention it extensively in connection with ranges, both in connection with toxicity to personnel and environmental (e.g. backstop construction for outdoor ranges). This is a manual of design best practices for safe construction and operation of a shooting range.

For example:

Indoor ranges require an internal atmosphere adequate to protect the health of workers as elevated blood lead levels are a potential threat to those who work in indoor ranges. Those who design and construct them must understand the cause of lead poisoning, the symptoms, the consequences of over-exposure and how to prevent it. It is equally important that they understand how to design ventilation systems for a particular shooting activity (see Section III, Chapter 2). You are strongly advised to engage the services of environmental engineers, architects, etc., to advise you.

Inhalation (breathing) and ingestion (swallowing) of airborne particulate lead is also a health issue to be aware of when on a shooting range. Protecting yourself through common sense and good personal hygiene is your responsibility. You owe it to yourself and to your family to take care of your health. After working or shooting on a shooting range, ALWAYS wash your hands, arms, and face before smoking or eating. If you fail to do this, you will be putting lead dust directly into your mouth.

And so forth.
