Why do circuit breakers go up for on and down for off?

There are some evolutionary advantages to red-green colorblindness. People with red-green color blindness can differentiate between much more shades of khaki than unaffected people. This might help detecting camouflaged food in a green environment [1]. Color vision deficient people have a tendency to have better night vision and, in some situations, they can perceive variations in luminosity that color-sighted people could not [2]. However, it’s important to note that colorblindness can also cause difficulties in everyday life [3].

That never happened. What actually happened was that half cast kids were removed to allegedly give them a better life and most did end up with a much better life.

But what was done in Australia had nothing to do with eugenics.

You can camp there presumably. Camping permanently would be living.

Because they're dangerous.

Not even close to the danger presented by humans. I don't think there are any wolves right in this area but there are black bears and cougars. I see them every now and then when walking through the woods. I feel safer than I would walking through many US cities.

I've never stayed in one place for 14 days with one exception. When I was a FS volunteer I lived all summer in the woods near the ranger station. The FS has some formal camping areas an a 'campground host' can settle in for the season. Unless I'm traveling I avoid them.

A friend lived in a popular recreational area for a couple of years. He maintained a low profile and avoided making visible trails to his campsite. It wasn't very far from a designated trail but most people don't go far from a trail.

I'm reading a novel 'Winter Games' by Daniel Church (not the British horror writer). It is set in the near future and the premise is dissident scientists film themselves in a temperature controlled room set to 59 F. There are fans to simulate an average wind speed of 7 mph. They are dressed in t-shirts or other light clothing. Their body temperature, heart rate and other metrics are displayed. Since a continuous webcam would be boring they only film a brief period every three hours. They are seated and do not exercise.

The filming goes on through various stages of hypothermia until their pulse rate falls to 0 and they are dead.

The significance of 59 F is that is the mean global temperature at the time that the climate alarmists are so concerned about. Given the conditions of the experiment humans will die at that temperature. Without artificial heating, be it a caveman's fire or the latest green energy scheme, and clothing, much of the earth is inhospitable to humans.

A wide range of temperatures is fine for a limited time.

When visiting somewhere in the countryside most people don't go that far away from their car.

I grew up within sight, from a high hill, of London. The roads were crowded, and the car parks by the nature trails full.

I used to cycle off road all day without meeting a single person. They never strayed much more than 400 yds from their cars

You would not die at 59F with a light breeze with a tshirt on. I take it you've never been camping.

59F isn't much below room temperature, and 7mph is like a desk fan next to you.

I've slept naked all night when it's snowing on the top of a mountain. You shiver, that's it.

You have the death sentence for those don't you?

Unless they're hungry and you're the only meat around.

The opposite is the Pacific Crest Trail, a roughly 3 month hike from Mexico to Canada. I've only done bits of it but have acted as a trail angel. What the hikers really appreciate is a cold beer.

There are places in San Franciso where one can take a (short) hike in the woods and see no people and no evidence of civilization. That's nice for a big city.

Think so? Do people name kids Herbert, knowing in advance that they will be gay?

I wouldn't name any kid Herbert.

And what's the obsession with gayness? That's telling.

Strange that a tiny place like England should have so many distinct accents.

"is" is too short. "a" is even worse.

It comes from a time when people very rarely traveled more than a few miles from home.

To a certain extent, those regional accents are smoothing out under the influence of radio and television. Just as in the U.S. Young Texans are more apt to speak "General American".

I'm from New Orleans and nobody can tell. I speak "NBC English."

Yes, US regional accents are fading. I think TV started that, and now there is a lot of migration between regions.

So many people going away to colleges, and getting jobs in cities, stirs things up too.

I rode a chair lift with a lady who had an astonishingly beautiful British accent, and then with a Russian guy who didn't.

It's sort of horrible what so many countries did to the elegant British accent.

In theory I should have a Western New England accent that's perceived around here as 'back east someplace' rather than General American.

How about Hubert, Norbert, Cuthbert, Gilbert, Filbert and so forth. It's odd the only *bert that survived is Robert, to the point of being a cliche. Albert is a distant second.

I did go to high school with a Hubert, who was black.
