Obsolete Advice (For things that still exist)

Manual transmissions rarely needed a “trans job”. That was much more a feature of early automatic transmissions.

Done right with good RPM matching, braking by downshifting should put negligible wear on a clutch. Just like proper RPM matching on upshifting does the same.

The fact most manual trans drivers both back in Ye Olden Dayes and even up to now don’t know how to, or don’t care to, do it right doesn’t negate the underlying logic that properly done downshift retardation puts negligible wear on clutch and brakes and trans.

Nowadays modern cars can last 100K miles no matter how much misuse / abuse drivers heap on them. Not so in Ye Olden Tymes of the 1950s or 1960s.

During my recent trip to Glasgow I couldn’t figure out why my computer wasn’t charging when it was plugged into the desk outlet. At first I had thought there was something wrong with my adapter. Then I saw the rocker switch next to the outlet, flipped it, and lo and behold the power light on my charger went on.

That FIV positive cats can’t live with FIV negative cats and/or should just be euthanized as soon as they test positive.

It’s outdated info.
In fact, they pass it through deep bite wounds, not normal grooming or sharing food. As long as they get along okay, they can live and hang out together. Also, it means very little in terms of how healthy the cat is.

In theory, minor illnesses like upper respiratory infections should hit them harder and take longer to recover from. But, having known approximately one gazillion FIV+ cats personally in an environment where pretty much every cat gets a URI at some point, the actual reality seems to be that there’s no difference between them and the FIV- cats in terms of illness and recovery.

They can be more prone to eventually having dental issues, but that’s about it. Other than that, they’re as likely as any other cat to live long, healthy lives. And they absolutely are adoptable.

(*feline leukemia and FIP are both different from FIV, although people often get them confused.)

My understanding is that too much protein can be bad for the liver, in the insane amounts that some bodybuilders take in. I don’t know whether it can be a problem for more reasonable (but still high) protein intake.

A sorta related obsolete piece of advice: avoid cholesterol, it’s a killer!

Cholesterol in the diet may not be as bad as was once believed. What clouds the matter is that some foods which contain cholesterol also contain lots of saturated fats (egg yolks, fat meat) which are AIUI more associated with heart disease than cholesterol.

So a person could eat lean meat and egg whites (which contain cholesterol but not much saturated fat) and be healthier than a vegan who ate foods with lots vegetable oils like palm and coconut (which contain no cholesterol but are high in saturated fats).

As always, there are genetic differences among individuals.

No there was absolutely advice given by consumer organizations (this was in the UK in the 90s, so probably “Which” or the BBC) that a website that didn’t have a clearly displayed physical address and phone number was disreputable and you should not enter your credit card number

That was stupid advice the very first time it was given. I’ve pulled more ticks off myself and my animals than I can count. It’s very simple and requires no more equipment than an opposable thumb. Just grab its nasty little neck, not the body, and pull directly out, there’s almost an audible click when the mouthparts let go of you – but there’s nothing that is going to convince a tick to ‘back out’, they are not constructed that way. All you’re going to do is kill the tick, and then it’s harder to pull them out without breaking off the mouthparts.

This is what obsolete nutritional advice always makes me think of:

My grandmother was afraid of lightning and would not allow windows to be opened that were across the room from each other. The idea being that the lightning could slide through and hit people on its way.

Goose grease was also recommended. Both were used along with the phrase “don’t use ice or cold water, that will drive the heat in.”

My guess is that ice numbed the nerve endings, taking the pain away. But when the ice was gone, the pain would come back. Which was interpreted as the heat coming back to the surface.

I drive a 2002 Saturn 5 speed manual with over 190K miles and I usually downshift when braking. I have done much maintenance and repair on the car over the years, but have never done anything with the clutch or transmission.

When I was younger in the 80’s, it seemed like every weekend some car needed some sort of maintenance or tune up. Replacing points, plugs, rotors, wires, filters, cleaning and adjusting a carburetor could take several hours. I’m down to a couple oil changes a year and can knock them out in under an hour.

That reminds me of the advice to change oil every 3k miles. With modern oils and filters, they can go 5k miles or more before changing.

That is not entirely untrue-

Breakfast kick-starts your metabolism, helping you burn calories throughout the day. It also gives you the energy you need to get things done and helps you focus at work or at school. Those are just a few reasons why it’s the most important meal of the day.

Many studies have linked eating breakfast to good health, including better memory and concentration, lower levels of “bad” LDL cholesterol, and lower chances of getting diabetes, heart disease, and being overweight.

It’s hard to know, though, if breakfast causes these healthy habits or if people who eat it have healthier lifestyles.

But this much is clear: Skipping the morning meal can throw off your body’s rhythm of fasting and eating. When you wake up, the blood sugar your body needs to make your muscles and brain work their best is usually low. Breakfast helps replenish it.

Yeah, but I know drives who use their automatic trans to slow down on hills… :crazy_face:

That is a great car. I have my SC2 to my wife, and she still drives it sometimes.

Really? I was under the impression (but have no cite) that it made some sense in the early days of automotive travel. (My father’s first car was a Model A.)

Materials technology, the reasoning went, was in a more primitive state then, and brake pads would wear out much faster, hence it was wise to spare them by engine braking when possible.

And of course it’s still reasonable on certain occasions involving a long downhill.

It used to be believed that stomach ulcers were caused by stress and/or spicy food. People with ulcers were advised to reduce stress in their life and eat a bland diet. In 1982 it was discovered that most stomach ulcers are in fact caused by a bacteria, Helicobacter pylori. Today ulcers are treated with antibiotics. No need to cut out the Mexican food or quit your job as a social worker.

You should brush your teeth with a vigorous up-and-down motion.

I have an aunt who still cooks pork to shoe leather to ensure that there’s no trichinosis. But trichinosis is all but nonexistent in commercial pork in the U.S. There are 20 cases per year on average in the U.S. and almost all of those are from wild game.

Not under a table. If something of significant size falls, it will squish you as it flattens the table. The best place to be, that is, the place that earthquake survivors are often found, is next to a bulky object, like a couch: if something big falls on you, it will tent against the couch, leaving you the space you need to not die.

I remember similar advice about measuring the supposed trustworthiness of a web shop by whether or not the padlock icon appeared in your browser (that is, whether the site used HTTPS); it was commonly asserted that you could trust them if it did - I think because of the assumption that whoever was issuing certificates was also auditing identities and trustworthiness.

People want there to be ‘one trick’* for how to reliably do any particular thing - I see it all over the place - not just in computing; in foraging of wild foods such as fungi, I am continually asked questions by people who appear to be assuming that there is some simple rule of thumb that will differentiate bad from good, or that for any given edible species, there will only be ‘one toxic lookalike’ that they have to learn about in order to be safe. But the world just isn’t arranged like that.

*I think this is why the ‘one weird trick’ clickbait was successful.

This message of ‘food and water don’t mix’ was so universal in the 70s/80s that my Mum wouldn’t even let us have a bath after eating.

Here’s my controversial obsolete advice, before my comments about others: Turn the lights of when you leave a room. With modern LED bulbs, it pretty much doesn’t matter. I’m not advocating turning every light on in the house like some kind of suburban quasar, but leaving a 5-7 watt LED bulb on 24/7 would cost about $5-15/year. Leave the lights on if you want to; an extra few hours a night leaving the kitchen lights on even though nobody is in there doesn’t take the kind of money that grows on trees.

Your transmission doesn’t care if it is transferring power from the engine to the wheels or from the wheels to the engine. That’s what it’s designed to do.

I’m not sure if that is supposed to be sarcastic or incredulous. Yes, please downshift in your automatic when descending long mountain passes so that you don’t overheat your brakes. Doing it for every red light does seem excessive.

I think the issue here is when everyone does this. One person is not a big deal. A 100 million people is probably a power plant or two (I didn’t do the math).

It’s like littering. If you are the only person who litters it really doesn’t register but when everyone litters it is a huge mess.

New born babies should be given evaporated milk.

I have my id tag from when I was born in 1967 it includes an advert for a Regal Evaporated Milk.

Apparently they had been a few cases of food poisoning through bacterial infections in sme infant formula so the medical advise became use evaporated milk as bacteria can not survive the heat when it is produced.
