It's simply untrue that "when the 2nd amendment was written only single shot muzzle loading pistols & rifles existed".
This article by David Kopel explores the firearms technologies available at the time:
"Firearms technology and the original meaning of the Second Amendment"
https://www.washingtonpost.com...

At the time the Second Amendment was written, it was not unusual for someone to make a firearm at home. About the only difference here is that technology has made it somewhat easier to make a firearm at home.

The video the article summarizes gives more details. It's a water-source heat pump. Water at 20 C is an excellent source for a heat pump.

Grocery Store? No masks. Rarely see anyone wearing a mask.
Doctor's office? No masks.
Dentist's office? No masks.
Endodontist's office? Masks.

YMMV.

"Third, it is possible that the association between a gun in the home and risk of a violent death may be related to other factors that we were unable to control for in our analysis. For instance, with homicide, the association may be related to certain neighborhood characteristics or the decedent’s previous involvement in other violent or illegal behaviors. Persons living in high-crime neighborhoods or involved in illegal behaviors may acquire a gun for protection. The risk comes not necessarily from the presence of the gun in the house but from these types of environmental factors and exposures."

So if you buy a gun because you live in a dangerous neighborhood, your increased risk of violent death may be due to where you live and not the gun you bought.

No. This is spike protein grown in yeast cells. Not the same as viruses grown in eggs.

My only regret in having read the Dirk Pitt series is that I can't read it again for the first time.

Intended to be a zombie novel with plausible science, the first part is eerily similar to the beginning of the COVID pandemic.

If we never spend resources on knowledge for knowledge alone, we'll never know what we might have done with that knowledge.

I suppose we could have kept living without any technology. No medicine, no farming, no solid-state electronics, no thermionic valves, no aluminum, steel, iron, copper or other metals, no flint knives. We could still all be huddling in small groups, wondering where our next meal was coming from.

I saw a really good auroral display while driving north on highway 41 in Wisconsin during late November. Viewing conditions were excellent - cold and clear. Watched them for about an hour before I got where I was going. Haven't seen as good a display since then.

From the Milwaukee Journal Sentinel September 28, 2013:
"Rifles will be allowed statewide for gun deer hunting seasons beginning Nov. 1, according to a Tuesday announcement from the Wisconsin Department of Natural Resources."

There is a local option, but I've not seen much news about it being exercised. You would want to check to be sure before deer hunting with a rifle, but most areas seem to allow rifle hunting.

Wisconsin law changed a while back. Areas that used to only allow shotguns with slugs for deer now generally allow rifles (there is a local option to require shotguns but as far as I know most areas went along with rifles). Part of the reason was that it was shown statistically that rifles were no more dangerous than shotguns. Counterintuitive, but true.

The article states 2 per 1000 for Covid-19, 6 per 1000 for 1918 flu.

Let's see.

1) When it's 90 F during the day I store the heat and pump it into my house when it's 80 F at night.

2) When it's 30 F during the day I store the heat and pump it into my house when it's 10 F at night.

Methinks there's a problem or two there someplace.
