You may not know *of* many but I bet you know quite a lot. It's about
8%
of men, although many of them do not realise that, or discover it until
tested later in life.

I think you'd notice when you saw all the traffic light bulbs looking
identical. You're not safe to drive if you can't tell red from green.


Very few are that colorblind


I've never heard of partial colourblindness,


Yes, you actually are that pig ignorant.
https://en.wikipedia.org/wiki/Color_blindness

mind you I've not heard of many colourblind people.


Yes, you actually are that pig ignorant.

I've seen it most with people who get rejected by the
military for being colourblind who had previously not
been aware that they were colourblind because the
problem is that small.

and those who are just use the position of the light, not the color.


Sounds bloody dangerous to me.


Yes, you actually are that pig ignorant.

Those who do the licensing of drivers so check that
you can do stuff like read a number plate at a distance
but they don't actually check that you can distinguish
between red and green lights, for a reason.

I use my full field of vision while driving. I can see pedestrians and
dogs moving in my peripheral vision. I can see a light turning red in my
peripheral vision.


And the tiny subset of those who can not distinguish
between red and green, are quite capable of glancing
at the traffic light to see which bulb is lit and still being
aware of where other cars are and of say a pedestrian
choosing to cross the road when they feel like it.

Dunno how they go with those colored arrows
that are now so common to indicate when you
can turn at the more complex intersections tho.


They're always on the side they're pointing to, and they can see the shape
surely?


The problem isnt the shape. Some of ours have
a single arrow beside the green which changes
from a red arrow to a green one when you are
allowed to make a turn there.

Cant find a proper photo of ours and too lazy to go there and take a
photo, but we have some
where there is a normal column of 3 lights and
one arrow off to the side which changes color
to indicate when you are free to turn there.
That often has the forward traffic stopped but
the turn allowed with a green arrow. And at
times the turn not allowed either with a red
arrow in the same place as the green one.


Ah, that sounds more complicated than ours.


Yeah, these are only at our more complicated
intersections, one which has the railway yards
shunting line going right across the multi lane
road, right at the lights themselves with a
large volume of traffic at both of them.

We just have red, amber, green in a column,


Yeah, most of ours are too.

then some have a green arrow stuck on the left (for left turns) and the
right (for right turns) of the green circular light.


That's what ours have to, but ours are either a red arrow
or a green arrow, and only the color of the arrow changes.

Presumably that's a recent thing now that they are all LED
lights so its easy to have the arrow color change now.

Mind you, our system can cause accidents. There was one near here where
sometimes you could go forwards but not right. The green circular light
came on, but not the green arrow. Many drivers assumed green circle, go
anywhere, and turned right into oncoming traffic.


Yeah, that's presumably why our arrows change
color, so that its always clear if you can turn or not.

They replaced the circular light with a forward arrow,


We don't have any like that here. Only
multiple color arrows for the turning lane.

which is much more sensible. Mind you, that junction was much more
efficient with no lights and a roundabout.


Ours with the complicated lights arent feasible to have
a roundabout. In the case of one of them the railway
yard shunting line goes right thru the intersection and
in the other there just isnt room for it.

We still put in new roundabout where that is feasible, but
they arent cheap with the big ones. Multiple megabucks.

Ours doesn't change colour. We have the normal three lights and maybe an
arrow at one side (sometimes both sides). If the main green is lit, but
not the turn arrow, you can turn anyway, but must give-way to oncoming
traffic. If the arrow is lit, oncoming traffic will be facing a red.
There
is no need for any other colour arrows.

Where the turn lane is separated from the straight on lanes, two full
sets
of three lights side by side are used.


One of our complicated intersections has the arrow either green or red.
Its red when the cross traffic has been allowed to make the turn into
that vertical of the T and so a turn from the other top bar of the T
isnt allowed because that would mean you have to give way at times.
In other words the lights don't require you to ever give way, the
arrow only shows green when there is never any conflicting traffic.


That would work well here, as a lot of drivers don't seem to understand
that you have to give way on a green. For example there's a crossroads
here I've shown befo
https://goo.gl/maps/8XGD49FnQPr
Drivers on the opposite side turning right have to give way to a car
coming from this side going straight ahead, but they see the green light
and just go. I drove straight towards one of those loonies the other week
and blasted my horn. He swerved out of my way and ended up looking very
embarrassed on the wrong side of the main road (about where the small
silver car is in the photo, but facing the other way) right in front of
the queue of traffic which shortly wanted to go forwards. He got stranded
in the middle of the junction for some time while I stopped and laughed at
his predicament.

Another complex intersection has a railway shunting line right
across it right at the lights. That one has an arrow that changes
color too and it stops or allows traffic to cut across the oncoming
traffic when turning. Its also a single arrow that changes color.


There's something wrong when we let trains have priority over cars.


Its done like that because they can't stop like cars can.

They need to get decent brakes.


Not even possible with any freight train. Plenty of
ours have 60 40' containers fully loaded. No brakes
will stop that in a few feet.

confirm which is which.


Correct. Which is why colour-blindness is not even notifiable to the
DVLA. Driving a train is of course totally different as braking needs to
be commenced way earlier and the position of the light cannot be
determined at that point.


I'm not colour blind, and I don't look directly at the traffic lights. I
see red or green out of the corner of my eye and act accordingly. If they
suddenly became the same or very similar colours,


That isnt what happens with most colorblind people.

And its never suddenly with any of them, they are born with it.

I'd make mistakes regularly.


Yes, some colorblind people do, but its normally only
with trivial stuff like not being able to pick matching
sox or less frequently wearing contrasting colors that
don't really go together that only normally sighted
people notice.

Are you saying a colour blind person already knows to look carefully at
things?


The microscopic subset of people that can't distinguish
between red and green do if fact use which of the
column of lights is lit instead of the color.

I can't think of where else colour and position are that important.


The most obvious is with signalling to aircraft
in the days before radio communication was
used. They used red or green light to indicate
whether you were allowed to land or not
depending on what else was using the runway.

The only colour blind person I know says red and green look IDENTICAL
(presumably in his eyes the red and green receptors are shorted together
somehow). They're only different if one is lighter than the other, but
then light green and light red are the same, and dark red and dark green
are the same, so that might depend on the traffic light design and the
position of the sun.


Interesting. According to wikipedia, some forms of color
blindness cant see red at all so that they can't even see that
the red light on a traffic light is lit, it looks like its not lit.
Tho they can see green fine, so all they have to do is
know that if no lights are visible, it must be showing red.

And that Romania does in fact ban the color blind from
driving. But the color blind are trying to get that overturned.

Usually hot is on the left.

Seems to be that way on all my sinks, but I'd say in other people's
houses I see it the other way round in about 20% of cases. When I
were
a lad, the bathroom sink was definitely the other way round, can't
remember the kitchen sink.

Back in the day when *cold* running water was a luxury, the tap
(fawcet)
would be mounted on the RHS for ease of use by right handed people
(the
majority of the population - most left handers learn soon enough to
become ambidextrous).

The hot tap being a much later luxury add on had to make do with
the
only remaining space on the LHS. Thus was the convention of LHS
hot/RHS
cold tap placement born. The other way round is usually the result of
lazy plumbing and pure chance.

Any evidence for that? Surely they would put the single tap in the
middle for symmetry. Was there ever a time when hot taps were added as
an extra to an existing cold water tap, rather than installing them
together?

I have seen te odd one like that yes, in pretty old un-renovated
properties back in the 1970s


Sounds like a neat, invented explanation.

That I agree with.

As soon as twin taps were vthe norm for some reaosn sonmeone decided
that the right hand more often than not wanted the cold tap

Depends on the person. I always wash my hands in cold water, I don't
see the need for hot water to dissolve a bar of soap. Some people
always use hot water, for comfort I think.

Prior to that the cold tap was generally either central or in an random
corner

Probably just depending in where the pipe happened to be. Why run it
further than necessary?

Mind you, you'd think a sink designed for one tap would have one hole,
in one place.


Sinks in them days didnt have holes

They were universally butlers type china basin with just a drain hole

Or maybe a galvabised tin thing - integrated tap holes and draining
boards are a massively later development.

My parents 1953 new build had a butltres sink on two brackets soldered
lead outflow pipe and a wooden draining board on IIRC both sides. I
can't remember whether it had a hot tap or not, or whether that was only
for the bath and two WC basins.


I do vaguely remember my grandmothers sink, in her house which I think she
lived in from marriage to death, the taps were fixed to the wall behind
the kitchen sink. I can't remember what the sink was like.


Yeah, I've certainly seen some like that, particularly in
the laundry with those big rectangular concrete sinks.
https://bathrenovationhq.com/wp-cont...inishing-2.jpg

In fact I can still remember my mum washing my arse in
one of those when I managed to crap my pants on the
way home from school when I must have been about 5.
And remember the turd was still there on the footpath
the next day when I walked back to school the next day.

And plenty of places like that wouldn't have had
a hot water tap but would have had the water
heated in a big copper thing for the washing.

By and large there was never any hot water unless monumental amounts of
coal were heaped on the dining room fire for an hour or so.,


Then a 2" deep bath used by the whole shivering family resulted.


Wouldn't it have been easier to go into the garden and hose each other?


Unlikely many would be too keen on that approach.

Or were garden hoses not available then?


Available, sure, but plenty of houses here just had
a rainwater tank that was filled from the roof with
a tap at the bottom of the tank that you filled things
from and wouldn't use that to water the garden with
a hose.

I wonder where this modern idea of "you must keep warm" came from.


Nothing modern about using a fire to keep warm.

Everyone survived cold things back then....


But werent actually stupid enough to
have a cold bath every day in winter.

There's a reason they had stuff like this
https://cdn.shopify.com/s/files/1/00...g?v=1373706131

In fact someone I know on the net said that her dad
had never had a bath or shower in his entire life. Yank.

Mostly hot water was boiled on a gas stove.

When it was invented is irrelevant. What matters is
whether it was actually required to be in the aircraft.
And even when it was very common in aircraft, it was
still used in the situation where the radio had failed.

Even you should have noticed traffic
lights do actually work during the day.
