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.

Corse there was.

Then you need a new hearing aid, bad.

Yet again you disagree without providing any reasoning or evidence for your point of view.

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. 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.

Mostly hot water was boiled on a gas stove.

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.

I suspect they don't look *identical*, just not as distinct as to
someone with normal colour vision. They would use the position to
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 think the appropriate response here is '********':

OK, not as central as I had fixed in my mind but the arm
itself is thin sheet metal which is creased along its length -
there probably a special way of describing this - to keep it
rigid, but the spectacle glass holder is a hefty lump of
metal, so the rear is still miuch heavier than the arm and
will still return it to danger.

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, I'd make mistakes regularly. Are you saying a colour blind person already knows to look carefully at things? I can't think of where else colour and position are that important.

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.
