People think of learning as something that happens primarily in the classroom. Still, our children learn how to “adult” by watching and being with us while we do our errands and by taking note of how we behave in any given situation.

..things always have a way of taking longer...
A generalization with no basis in fact.
In IT I go into a large shop. A job that must run daily takes over 60 hours to run. They blame DB2. They implement some of my suggestions and it runs in 3 minutes. It they had implemented all of my suggestions it would run closer to 3 seconds.
In another shop my suggestions reduce 1 12 month project to 3 months...and that is only because I made the suggestios in month 2.
Repeadtedly things take longer due to poor design, poor understanding of the situation.
As a consultant I see that many HR and management have the goal of perpetual employment by not solving the problem. Solving the problem would make them jobless.
They have learned so little that it is too late to teach them.
I gave up when challenged with some in the supposedly adult based industrial education classes I taught. So many of the students lacked basic education skills or what should be common tribal knowledge for adults there were just not enough hours in a class to teach them anything related to what they were supposedly there to learn.
Remedial and filler instruction took all the time available for most. I tried but had to give up and tell them they were in over their heads and tell their supervisors the same things. I had to do this so that people there who were able to lean could learn what they came for.
I am happy to be out of that business now. I never want to return to it. It broke my spirit of loving to teach.
Really in the modern world maps are worthless.
Try going to northern Arizona where there is no cell service. All you see is your car's marker on a grid. No turn directions are uttered. We had paper maps and did just fine.
90% of the lightbulbs will never be replaced anymore.
My LED light bulbs must be replaced more often that the incandescent ones required.
garages are going away
That is ridiculous.
Once upon a time the GOP’s ground game skills in vote by mail were considered one of their biggest advantages in AZ. Maybe the GOP should remember their old skills.
Actually I used my cellphone to get all the way from Tucson to the Grand Canyon. Never had a problem with cell service.
If your LED bulbs are breaking you light is a problem. LED bulbs literally cannot burn out, there’s nothing to burn out. Something might be shorting in there, but that’s on what you’re screwing them into. Heck I’ve got a bunch of LED lights where you CAN’T replace the bulbs, it’s a sealed unit.
Not ridiculous at all. More and more new houses aren’t being built with garages. They ARE going away.
You probably live someplace that doesn't stack ice upon your car during the winter.
Melting isn’t overheating. And, as I said, that would be a problem with the socket, or specifically what’s around the socket. If your socket is making your LEDs melt faster than incandescent burn out, then your socket is a fire hazard. Replace it with something that doesn’t suck.
That is ludicrous! Melting IS associated with heat. Do you know there are molecular-sized things going on inside an LED? The diode junction is but a few molecular layers thick. It can melt without any obvious damage when observed by eye.
LED lights are poorly designed, like most everything else from China. All it takes is for the LED die to be mounted on its heat sink with an insufficient amount of heat conductive glue. It is also possible to compound that glue incorrectly so that it doesn't conduct heat well enough to keep the junction cool. The heat sink itself can be undersized or not positioned properly to get airflow to take the heat away. The airflow in the fixture can be restricted so the airflow isn't fast enough. Before you give me a song and dance about airflow, we are talking convection cooling.
That was a brain fart. I meant melting isn’t burning out.
LED lights are FINE. Your sockets on the other hand... I’ve got an exterior LED light (sealed, only way to replace the bulb is to buy a whole new unit) on the south facing side of my house, in Tucson. If LED lights had a melting problem I’d have to replace that thing multiple times a summer. Never replaced it. I have unreplaceable LED lights in the kitchen. Never replaced. I’ve never replaced a single LED. Sealed or bulb. EVER. I work in the computer industry, I’ve got 25 year old equipment with rows and rows of LEDs, never had one stop working.
If you’re replacing your LEDs all the time you’re buying crap products, or putting them in crap sockets. PERIOD.
They come from Home Depot, just like yours.
Then what you’re screwing them into is busted, and a fire hazard, and you should replace it.
Of course even at Home Depot there’s the cheap crap and the good stuff. And honestly, I often don’t even do Home Depot cause even their good stuff ain’t all that. When I bought ceiling fans last year I went to the lighting store, cost way more than Home Depot, but I know they will run silently and perfectly for years. Which no Home Depot fan I’ve gotten has ever done. Oh and they have sealed lighting kits with LEDs in em too. Really, if your LEDs are dying that’s on you. You got crappy stuff.
Me too. I design electronic devices, and write the software that goes into them. I must consider operating currents and resultant temperature rises for all of the components used in the designs.
I have a shop in my basement that had 12 8ft long fluorescent light fixtures. They were always a bit noisy, but made light for 21 years before they started to bite the dust. I replaced them all with LED versions. Those are quiet, make a lot of very nice light. I like them. Two have failed only one year after installation.
The LEDs used used as indicator lamps in equipment draw around 10 milliamps with 2.1 volts across the junction. That is about 21 milli-watts. That will stay really cool and last virtually forever. The LEDs used in lighting are operated around 3000 milli-amps, which is about 6.3 watts. (Not milli-watts) That causes a significant temperature rise at the junction. Heat must be conducted away from the device as quickly as possible because something that small will suffer rapid gain to very high temperatures. The diode crystal can melt or the chemical composition of the junction will change at high temperatures.
Most consumer products are designed at the lowest engineering standards that will meet the need. The idea is reduce production costs in order to maximize the sales margin. This done simply by compromising the amount or quality of materials used. My observations tell me that they skimp on the size of the aluminum heat sinks on which the LED dies (crystals) are mounted.
And yet NONE of mine have EVER needed replacing. Even the one that eats Tucson sun all day.
It’s not your bulbs, it’s what you’re putting them in. And really, if it’s melting your bulbs it’s gonna burn your house down. Save your own life, fix your lights.
“I suppose it’s now worthless to teach someone how to start their car with a manual transmission by popping the clutch while its rolling….”
I’ve always had trouble getting the vehicle to roll fast enough with my foot out the driver’s door.
I have personally observed that teenagers don’t know to use doorbells.
how to turn off the toilet water input...!!!
“...there’s a Fob...”
Thieves can buy a device that can remotely scan and download the fob’s information from a distance. They can drive through apartment complexes and get the info from the fob sitting in someone’s apartment. Then later they drive through the lot and see which car lights come on when they activate the fake fob.

Download your own “offline maps” before the trip using Google Maps or Google Maps for iPhone or something similar.
Oh, God, yes! Usually in a galloping-door-slamming hurry.
Garmons are better GPS devices than any phone. Paper maps are still the best. There are many failure points for GPS navigation, none for maps and compass. (Except old fashioned brain farts.) I’m very fond of USGS Quads. When I travel I always bring Delmore map books along, one for each state I visit. They help find more interesting places than Internet searches can turn up.
I use all three when in remote areas: paper maps, downloaded maps, dedicated GPS device.
Me too. Paper maps will remain even after our civilization collapses. (Its happening) Keep your map & compass skills.
