Stainless steel does not mean it will not stain or rust, merely that it is less likely to or will be slower to do so.  I have some stainless steel eating utensils that are rusting because PA insists on letting them soak for obscene lengths of time.
A good monarch is a treasure. A good politician is an oxymoron.

My brain is both uninhibited and uninhabited.

I only wash my hands in public restrooms if the sink, the dispenser and the drying device are all mechanical.
Sometimes I have to use my shirt to open the door.

Yeah. If you touch the door, it negates the hand washing.
Can't you guys even just imagine it?

Forget practicality, or your experience....can you just....imagine?

It's there. It always was.

I use gloves as long as possible to avoid touching doorhandles in public places at all.

Well, I wear gloves during the cold time of the year, which here is from about early October to early April.

The best way to chase away an annoying wasp, is to slowly, non-abruptly push it away from yourself, with your hand.
Key is slow movement, try to imitate the speed of a branch waving in the wind.
The wasp does not comprehend that you are a living thing, it merely reacts to movements. Quick abrupt movements are typical of predators, such as birds, and will cause the wasp to strike.
Slow movements are typical of plants waving in the wind, and will annoy the wasp, and make it fly to elsewhere.

Tested. :M
does this work with all flying stingy insects?

No, it doesn't, alas.
I can do upside down chocolate moo things!

Have one pair that is the only one that accepts cock bugs.  And a clean pair for your steering wheel.

WHO WAS KILROY?

He is engraved in stone in the National War Memorial in Washington, DC. It's back in a small alcove where very few people have seen it. A bit of trivia - even if you never heard of Kilroy before.

For the WWII generation, this will bring back memories. For you younger folks, it's a bit of trivia that is a part of our American history.

Anyone born in 1913 to about 1950, is familiar with Kilroy. We didn't know why, but we had lapel pins with his nose hanging over the label and the top of his face above his nose with his hands hanging over the label. No one knew why he was so well known, but we all joined in!

So who the heck was Kilroy?

In 1946 the American Transit Association, through its radio program, "Speak to America ," sponsored a nationwide contest to find the real Kilroy, offering a prize of a real trolley car to the person who could prove himself to be the genuine article. Almost 40 men stepped forward to make that claim, but only James Kilroy from Halifax, Massachusetts, had evidence of his identity.

Kilroy was a 46-year old shipyard worker during the war who worked as a checker at the Fore River Shipyard in Quincy. His job was to go around and check on the number of rivets completed. Riveters were on piecework and got paid by the rivet. He would count a block of rivets and put a check mark in semi-waxed lumber chalk, so the rivets wouldn't be counted twice. When Kilroy went off duty, the riveters would erase the mark.

Later on, an off-shift inspector would come through and count the rivets a second time, resulting in double pay for the riveters.

One day Kilroy's boss called him into his office. The foreman was upset about all the wages being paid to riveters, and asked him to investigate. It was then he realized what had been going on. The tight spaces he had to crawl in to check the rivets didn't lend themselves to lugging around a paint can and brush, so Kilroy decided to stick with the waxy chalk. He continued to put his check mark on each job he inspected, but added 'KILROY WAS HERE' in king-sized letters next to the check, and eventually added the sketch of the chap with the long nose peering over the fence and that became part of the Kilroy message.

Once he did that, the riveters stopped trying to wipe away his marks. Ordinarily the rivets and chalk marks would have been covered up with paint. With the war on, however, ships were leaving the Quincy Yard so fast that there wasn't time to paint them. As a result, Kilroy's inspection "trademark" was seen by thousands of servicemen who boarded the troopships the yard produced.

His message apparently rang a bell with the servicemen, because they picked it up and spread it all over Europe and the South Pacific.

Before war's end, "Kilroy" had been here, there, and everywhere on the long hauls to Berlin and Tokyo. To the troops outbound in those ships, however, he was a complete mystery; all they knew for sure was that someone named Kilroy had "been there first." As a joke, U.S. servicemen began placing the graffiti wherever they landed, claiming it was already there when they arrived.

Kilroy became the U.S. super-GI who had always "already been" wherever GIs went. It became a challenge to place the logo in the most unlikely places imaginable (it is said to be atop Mt. Everest, the Statue of Liberty, the underside of the Arc de Triomphe, and even scrawled in the dust on the moon.

As the war went on, the legend grew. Underwater demolition teams routinely sneaked ashore on Japanese-held islands in the Pacific to map the terrain for coming invasions by U.S. troops (and thus, presumably, were the first GI's there). On one occasion, however, they reported seeing enemy troops painting over the Kilroy logo!

In 1945, an outhouse was built for the exclusive use of Roosevelt, Stalin, and Churchill at the Potsdam conference. Its' first occupant was Stalin, who emerged and asked his aide (in Russian), "Who is Kilroy?"

To help prove his authenticity in 1946, James Kilroy brought along officials from the shipyard and some of the riveters. He won the trolley car, which he gave to his nine children as a Christmas gift and set it up as a playhouse in the Kilroy front yard in Halifax, Massachusetts.

So, now you know.

What makes rain smell so good?


Step outside after the first storm after a dry spell and it invariably hits you: the sweet, fresh, powerfully evocative smell of fresh rain.

If you’ve ever noticed this mysterious scent and wondered what’s responsible for it, you’re not alone.

Back in 1964, a pair of Australian scientists (Isabel Joy Bear and R. G. Thomas) began the scientific study of rain’s aroma in earnest with an article in Nature titled “Nature of Agrillaceous Odor.” In it, they coined the term petrichor to help explain the phenomenon, combining a pair of Greek roots: petra (stone) and ichor (the blood of gods in ancient myth).

In that study and subsequent research, they determined that one of the main causes of this distinctive smell is a blend of oils secreted by some plants during arid periods. When a rainstorm comes after a drought, compounds from the oils—which accumulate over time in dry rocks and soil—are mixed and released into the air. The duo also observed that the oils inhibit seed germination, and speculated that plants produce them to limit competition for scarce water supplies during dry times.

These airborne oils combine with other compounds to produce the smell. In moist, forested areas in particular, a common substance is geosmin, a chemical produced by a soil-dwelling bacteria known as actinomycetes. The bacteria secrete the compound when they produce spores, then the force of rain landing on the ground sends these spores up into the air, and the moist air conveys the chemical into our noses.

“It’s a very pleasant aroma, sort of a musky smell,” soil specialist Bill Ypsilantis told NPR during an interview on the topic. “You’ll also smell that when you are in your garden and you’re turning over your soil.”

Because these bacteria thrive in wet conditions and produce spores during dry spells, the smell of geosmin is often most pronounced when it rains for the first time in a while, because the largest supply of spores has collected in the soil. Studies have revealed that the human nose is extremely sensitive to geosmin in particular—some people can detect it at concentrations as low as 5 parts per trillion. (Coincidentally, it’s also responsible for the distinctively earthy taste in beets.)

Ozone—O3, the molecule made up of three oxygen atoms bonded together—also plays a role in the smell, especially after thunderstorms. A lightning bolt’s electrical charge can split oxygen and nitrogen molecules in the atmosphere, and they often recombine into nitric oxide (NO), which then interacts with other chemicals in the atmosphere to produce ozone. Sometimes, you can even smell ozone in the air (it has a sharp scent reminiscent of chlorine) before a storm arrives because it can be carried over long distances from high altitudes.

But apart from the specific chemicals responsible, there’s also the deeper question of why we find the smell of rain pleasant in the first place. Some scientists have speculated that it’s a product of evolution.

Anthropologist Diana Young of the University of Queensland in Australia, for example, who studied the culture of Western Australia’s Pitjantjatjara people, has observed that they associate the smell of rain with the color green, hinting at the deep-seated link between a season’s first rain and the expectation of growth and associated game animals, both crucial for their diet. She calls this “cultural synesthesia”—the blending of different sensory experiences on a society-wide scale due to evolutionary history.

It’s not a major leap to imagine how other cultures might similarly have positive associations of rain embedded in their collective consciousness—humans around the world, after all, require either plants or animals to eat, and both are more plentiful in rainy times than during drought. If this hypothesis is correct, then the next time you relish the scent of fresh rain, think of it as a cultural imprint, derived from your ancestors.
